Regex Match a string that is indirectly bound by 2 strings
Here is my abstracted test string:
test test test
blue
test test test
red 23
test test test
grey
test test test
blue
test test test
red 99
test test test
grey - white
test test test
I am trying to match the text between the second "blue" and "grey - white"
Basically I'm parsing some code, and need 2 rules:
1.) Find red if between "blue" and "grey"
2.) Find red if between "blue" and "grey - white" * I can't be sure of the order of the stanzas
The first one isn't too hard: Link
But I can't figure out the second rule. Everything I tried...
like (?s)(blue)(.*?)(grey(?!s+test))
... still matches the first "blue", instead of skipping over it
Is there away to turn (.*?) into 'but only if does not contain "blue" '
Anyone know a trick I do not?

I believe you are looking for this based on your 2 rules although they don't match your regex. regex101
(blue).*?[^ ](red) .*?[^ ](grey( | - blue)?)
Match 'blue' followed by a non greedy match of anything until the next 'red' (where red is proceeded by the start of a line or a space, and followed by a space) followed by a non-greedy match of anything until followed by 'grey' (where grey is proceeded by the start of a line or a space) which is itself optionally followed by a space or ' - blue'. Ensuring the match word is proceeded by a space rules out false matches where 'red' is part of another word.

(?s)(blue).*?(red).*?(grey(?: - blue)?)
The above regex matches BOTH reds... but I need to be able to tell which is which (I can't rely on their order)
.
Let me re-write the question to clarify the objective:
I need two regex, I already found an answer for 1.), but am looking for an answer for 2.):
1.) Find "red XX" if between "blue" and "grey" (match contains only red 23)
2.) Find "red XX" if between "blue" and "grey - white" (match contains only red 99)

This regex (?s)(blue)(.*?)(grey(?!s+test)) will match the whole part between the first blue and the last grey because of the negative lookahead (grey(?!s+test)) which does match in the middle and fails the negative lookahead.
What you might do is capture blue and then use a greedy match to match the last "red" followed by 1+ digits. Then use a non greedy pattern to match until the first "grey - white"
(?s)(blue).*(red d+).*?(grey - white)
