Question

How can I print color in console? I want to show data in colors when the processor sends data and in different colors when it receives data.

If your terminal supports it, you can use ANSI escape codes to use color in your output. It generally works for Unix shell prompts; however, it doesn't work for Windows Command Prompt (Although, it does work for Cygwin). For example, you could define constants like these for the colors:

public static final String ANSI_RESET = "u001B[0m";

public static final String ANSI_BLACK = "u001B[30m";

public static final String ANSI_RED = "u001B[31m";

public static final String ANSI_GREEN = "u001B[32m";

public static final String ANSI_YELLOW = "u001B[33m";

public static final String ANSI_BLUE = "u001B[34m";

public static final String ANSI_PURPLE = "u001B[35m";

public static final String ANSI_CYAN = "u001B[36m";

public static final String ANSI_WHITE = "u001B[37m";

Then, you could reference those as necessary.

For example, using the above constants, you could make the following red text output on supported terminals:

System.out.println(ANSI_RED + "This text is red!" + ANSI_RESET);

Update: You might want to check out the Jansi library. It provides an API and has support for Windows using JNI. I haven't tried it yet; however, it looks promising.

Update 2: Also, if you wish to change the background color of the text to a different color, you could try the following as well:

public static final String ANSI_BLACK_BACKGROUND = "u001B[40m";

public static final String ANSI_RED_BACKGROUND = "u001B[41m";

public static final String ANSI_GREEN_BACKGROUND = "u001B[42m";

public static final String ANSI_YELLOW_BACKGROUND = "u001B[43m";

public static final String ANSI_BLUE_BACKGROUND = "u001B[44m";

public static final String ANSI_PURPLE_BACKGROUND = "u001B[45m";

public static final String ANSI_CYAN_BACKGROUND = "u001B[46m";

public static final String ANSI_WHITE_BACKGROUND = "u001B[47m";

For instance:

System.out.println(ANSI_GREEN_BACKGROUND + "This text has a green background but default text!" + ANSI_RESET);

System.out.println(ANSI_RED + "This text has red text but a default background!" + ANSI_RESET);

System.out.println(ANSI_GREEN_BACKGROUND + ANSI_RED + "This text has a green background and red text!" + ANSI_RESET);

@WhiteFang34 Can you please explain what is the use of RESET if its color is BLACK, at least in my console? Is it like a default or sth.? — Apr 23 '11 at 8:31
@Boro: the reset code turns off all ANSI attributes set so far, which should return the console to its defaults. It's useful if you don't know the default color or are also using some of the other attributes like background color, font styles, etc. — Apr 23 '11 at 8:38
jansi is really great! for those who develop in eclipse, i can reccomend this plugin: mihai-nita.net/2013/06/03/eclipse-plugin-ansi-in-console and nice piece of code to enable color if the code isn't being executed in console: if (System.console() == null) System.setProperty("jansi.passthrough", "true"); — Apr 13 '14 at 19:51

I created a library called JCDP (Java Colored Debug Printer).

For Linux it uses the ANSI escape codes that WhiteFang mentioned, but abstracts them using words instead of codes which is much more intuitive. It becomes as easy as:

print("Hello World!", Attribute.BOLD, FColor.YELLOW, BColor.GREEN);

For Windows it actually includes the JAnsi library but creates an abstraction layer over it, maintaining the intuitive and simple interface created for Linux.

This library is licensed under the MIT License so feel free to use it.

Have a look at JCDP's github repository.

Here are a list of colors in a Java class with public static fields

Usage

System.out.println(ConsoleColors.RED + "RED COLORED" +

A fairly portable way of doing it is with the raw escape sequences. See http://en.wikipedia.org/wiki/ANSI_escape_code

[edited for user9999999 on 2017-02-20]

Java doesn't "handle the codes", that's true, but Java outputs what you told it to output. it's not Java's fault that the Windows console treats ESC (chr(27)) as just another glyph (←).

which doesn't work because the Java IO layer does not convert those to colors. System.out.println((char)27 + "[31;1mERROR" + (char)27 + "[0m" only yields "[31;1mERROR[0m" when run from a windows cmd.com as an executable .jar

You could do this using ANSI escape sequences. I've actually put together this class in Java for anyone that would like a simple workaround for this. It allows for the use of custom color codes in text.

https://gist.github.com/nathan-fiscaletti/9dc252d30b51df7d710a

Example Use:

Color code format WITH background color -> :foreground,background:

Color code format WITHOUT background color -> :foreground,N:

Reset Color format -> [RC]

String ansiColoredString = ColorCodes.parseColors("Hello, This :blue,n:is[RC] a :red,white:response[RC].");

or

String ansiColoredString = ColorCodes.RED + "Hello" + ColorCodes.WHITE + ", This is a " + ColorCodes.BLUE + "test";

If you use Kotlin (which works seamlessly with Java), you can make such an enum:

enum class AnsiColor(private val colorNumber: Byte) {

    BLACK(0), RED(1), GREEN(2), YELLOW(3), BLUE(4), MAGENTA(5), CYAN(6), WHITE(7);



    companion object {

        private const val prefix = "u001B"

        const val RESET = "$prefix[0m"

        private val isCompatible = "win" !in System.getProperty("os.name").toLowerCase()

    }



    val regular get() = if (isCompatible) "$prefix[0;3${colorNumber}m" else ""

    val bold get() = if (isCompatible) "$prefix[1;3${colorNumber}m" else ""

    val underline get() = if (isCompatible) "$prefix[4;3${colorNumber}m" else ""

    val background get() = if (isCompatible) "$prefix[4${colorNumber}m" else ""

    val highIntensity get() = if (isCompatible) "$prefix[0;9${colorNumber}m" else ""

    val boldHighIntensity get() = if (isCompatible) "$prefix[1;9${colorNumber}m" else ""

    val backgroundHighIntensity get() = if (isCompatible) "$prefix[0;10${colorNumber}m" else ""

}

And then use is as such: (code below showcases the different styles for all colors)

val sampleText = "This is a sample text"

enumValues<AnsiColor>().forEach { ansiColor ->

    println("${ansiColor.regular}$sampleText${AnsiColor.RESET}")

    println("${ansiColor.bold}$sampleText${AnsiColor.RESET}")

    println("${ansiColor.underline}$sampleText${AnsiColor.RESET}")

    println("${ansiColor.background}$sampleText${AnsiColor.RESET}")

    println("${ansiColor.highIntensity}$sampleText${AnsiColor.RESET}")

    println("${ansiColor.boldHighIntensity}$sampleText${AnsiColor.RESET}")

    println("${ansiColor.backgroundHighIntensity}$sampleText${AnsiColor.RESET}")

}

If running on Windows where these ANSI codes are not supported, the isCompatible check avoids issues by replacing the codes with empty string.

The best way to color console text is to use ANSI escape codes. In addition of text color, ANSI escape codes allows background color, decorations and more.

Unix

If you use springboot, there is a specific enum for text coloring: org.springframework.boot.ansi.AnsiColor

Jansi library is a bit more advanced (can use all the ANSI escape codes fonctions), provides an API and has a support for Windows using JNA.

Otherwise, you can manually define your own color, as shown is other responses.

Windows 10

Windows 10 (since build 10.0.10586 - nov. 2015) supports ANSI escape codes (MSDN documentation) but it's not enabled by default. To enable it:

With SetConsoleMode API, use ENABLE_VIRTUAL_TERMINAL_PROCESSING (0x0400) flag. Jansi uses this option.

If SetConsoleMode API is not used, it is possible to change the global registry key HKEY_CURRENT_USERConsoleVirtualTerminalLevel by creating a dword and set it to 0 or 1 for ANSI processing:
"VirtualTerminalLevel"=dword:00000001

Before Windows 10

Windows console does not support ANSI colors. But it's possible to use console which does.

If your terminal supports it, you can use ANSI escape codes to use color in your output. It generally works for Unix shell prompts; however, it doesn't work for Windows Command Prompt (Although, it does work for Cygwin). For example, you could define constants like these for the colors:

public static final String ANSI_RESET = "u001B[0m";

public static final String ANSI_BLACK = "u001B[30m";

public static final String ANSI_RED = "u001B[31m";

public static final String ANSI_GREEN = "u001B[32m";

public static final String ANSI_YELLOW = "u001B[33m";

public static final String ANSI_BLUE = "u001B[34m";

public static final String ANSI_PURPLE = "u001B[35m";

public static final String ANSI_CYAN = "u001B[36m";

public static final String ANSI_WHITE = "u001B[37m";

Then, you could reference those as necessary.

For example, using the above constants, you could make the following red text output on supported terminals:

System.out.println(ANSI_RED + "This text is red!" + ANSI_RESET);

Update: You might want to check out the Jansi library. It provides an API and has support for Windows using JNI. I haven't tried it yet; however, it looks promising.

Update 2: Also, if you wish to change the background color of the text to a different color, you could try the following as well:

public static final String ANSI_BLACK_BACKGROUND = "u001B[40m";

public static final String ANSI_RED_BACKGROUND = "u001B[41m";

public static final String ANSI_GREEN_BACKGROUND = "u001B[42m";

public static final String ANSI_YELLOW_BACKGROUND = "u001B[43m";

public static final String ANSI_BLUE_BACKGROUND = "u001B[44m";

public static final String ANSI_PURPLE_BACKGROUND = "u001B[45m";

public static final String ANSI_CYAN_BACKGROUND = "u001B[46m";

public static final String ANSI_WHITE_BACKGROUND = "u001B[47m";

For instance:

System.out.println(ANSI_GREEN_BACKGROUND + "This text has a green background but default text!" + ANSI_RESET);

System.out.println(ANSI_RED + "This text has red text but a default background!" + ANSI_RESET);

System.out.println(ANSI_GREEN_BACKGROUND + ANSI_RED + "This text has a green background and red text!" + ANSI_RESET);

@WhiteFang34 Can you please explain what is the use of RESET if its color is BLACK, at least in my console? Is it like a default or sth.? — Apr 23 '11 at 8:31

Here are a list of colors in a Java class with public static fields

Usage

System.out.println(ConsoleColors.RED + "RED COLORED" +

ConsoleColors.RESET + " NORMAL");

Note
Don't forget to use the RESET after printing as the effect will remain if it's not cleared

public class ConsoleColors {

    // Reset

    public static final String RESET = "33[0m";  // Text Reset



    // Regular Colors

    public static final String BLACK = "33[0;30m";   // BLACK

A fairly portable way of doing it is with the raw escape sequences. See http://en.wikipedia.org/wiki/ANSI_escape_code

[edited for user9999999 on 2017-02-20]

Java doesn't "handle the codes", that's true, but Java outputs what you told it to output. it's not Java's fault that the Windows console treats ESC (chr(27)) as just another glyph (←).

you made me boot into Windows. you owe me, bro

which doesn't work because the Java IO layer does not convert those to colors. System.out.println((char)27 + "[31;1mERROR" + (char)27 + "[0m" only yields "[31;1mERROR[0m" when run from a windows cmd.com as an executable .jar

the question wasn't tagged windows. the Windows console was never ANSI-compliant that I remember.

but the issue is that java isn't handling the codes, regardless of cmd.com's support

You could do this using ANSI escape sequences. I've actually put together this class in Java for anyone that would like a simple workaround for this. It allows for the use of custom color codes in text.

https://gist.github.com/nathan-fiscaletti/9dc252d30b51df7d710a

Example Use:

Color code format WITH background color -> :foreground,background:

Color code format WITHOUT background color -> :foreground,N:

Reset Color format -> [RC]

String ansiColoredString = ColorCodes.parseColors("Hello, This :blue,n:is[RC] a :red,white:response[RC].");

or

String ansiColoredString = ColorCodes.RED + "Hello" + ColorCodes.WHITE + ", This is a " + ColorCodes.BLUE + "test";

If anyone is looking for a quick solution, feel free to use the following helper class :)

public class Log {



    public static final String ANSI_RESET = "u001B[0m";

    public static final String ANSI_BLACK = "u001B[30m";

    public static final String ANSI_RED = "u001B[31m";

    public static final String ANSI_GREEN = "u001B[32m";

    public static final String ANSI_YELLOW = "u001B[33m";

    public static final String ANSI_BLUE = "u001B[34m";

    public static final String ANSI_PURPLE = "u001B[35m";

    public static final String ANSI_CYAN = "u001B[36m";

    public static final String ANSI_WHITE = "u001B[37m";



    //info

    public static void i(String className, String message) {

        System.out.println(ANSI_GREEN + className + " : " + message + ANSI_RESET);

    }



    //error

    public static void e(String className, String message) {

        System.out.println(ANSI_RED + className + " : " + message + ANSI_RESET);

    }



    //debug

    public static void d(String className, String message) {

        System.out.println(ANSI_BLUE + className + " : " + message + ANSI_RESET);

    }



    //warning

    public static void w(String className, String message) {

        System.out.println(ANSI_YELLOW + className + " : " + message + ANSI_RESET);

    }



}

USAGE:

Log.i(TAG,"This is an info message");



Log.e(TAG,"This is an error message");



Log.w(TAG,"This is a warning message");



Log.d(TAG,"This is a debug message");

Thanks @whiteFang34 for the ANSI codes.

If you use Kotlin (which works seamlessly with Java), you can make such an enum:

enum class AnsiColor(private val colorNumber: Byte) {

    BLACK(0), RED(1), GREEN(2), YELLOW(3), BLUE(4), MAGENTA(5), CYAN(6), WHITE(7);



    companion object {

        private const val prefix = "u001B"

        const val RESET = "$prefix[0m"

        private val isCompatible = "win" !in System.getProperty("os.name").toLowerCase()

    }



    val regular get() = if (isCompatible) "$prefix[0;3${colorNumber}m" else ""

    val bold get() = if (isCompatible) "$prefix[1;3${colorNumber}m" else ""

    val underline get() = if (isCompatible) "$prefix[4;3${colorNumber}m" else ""

    val background get() = if (isCompatible) "$prefix[4${colorNumber}m" else ""

    val highIntensity get() = if (isCompatible) "$prefix[0;9${colorNumber}m" else ""

    val boldHighIntensity get() = if (isCompatible) "$prefix[1;9${colorNumber}m" else ""

    val backgroundHighIntensity get() = if (isCompatible) "$prefix[0;10${colorNumber}m" else ""

}

And then use is as such: (code below showcases the different styles for all colors)

val sampleText = "This is a sample text"

enumValues<AnsiColor>().forEach { ansiColor ->

    println("${ansiColor.regular}$sampleText${AnsiColor.RESET}")

    println("${ansiColor.bold}$sampleText${AnsiColor.RESET}")

    println("${ansiColor.underline}$sampleText${AnsiColor.RESET}")

    println("${ansiColor.background}$sampleText${AnsiColor.RESET}")

    println("${ansiColor.highIntensity}$sampleText${AnsiColor.RESET}")

    println("${ansiColor.boldHighIntensity}$sampleText${AnsiColor.RESET}")

    println("${ansiColor.backgroundHighIntensity}$sampleText${AnsiColor.RESET}")

}

If running on Windows where these ANSI codes are not supported, the isCompatible check avoids issues by replacing the codes with empty string.

The best way to color console text is to use ANSI escape codes. In addition of text color, ANSI escape codes allows background color, decorations and more.

Unix

If you use springboot, there is a specific enum for text coloring: org.springframework.boot.ansi.AnsiColor

Jansi library is a bit more advanced (can use all the ANSI escape codes fonctions), provides an API and has a support for Windows using JNA.

Otherwise, you can manually define your own color, as shown is other responses.

Windows 10

Windows 10 (since build 10.0.10586 - nov. 2015) supports ANSI escape codes (MSDN documentation) but it's not enabled by default. To enable it:

With SetConsoleMode API, use ENABLE_VIRTUAL_TERMINAL_PROCESSING (0x0400) flag. Jansi uses this option.

If SetConsoleMode API is not used, it is possible to change the global registry key HKEY_CURRENT_USERConsoleVirtualTerminalLevel by creating a dword and set it to 0 or 1 for ANSI processing:
"VirtualTerminalLevel"=dword:00000001

Before Windows 10

Windows console does not support ANSI colors. But it's possible to use console which does.
