[Scripting Question] Change colors by default in messages?

Hey,
I'm trying to change the windowskin to a dark one, but as you must think, I also have to change default colors to fit it, like the blue you obtain using \b should be lighter, like the red you obtain by using \r.

So I checked some tutorials and I changed this part of spritewindow

"<c3=b3daff,c9cbd1>", # Blue
"<c3=ffb3b3,d0c8c8>", # Red
"<c3=b3ffcc,c9d1c9>", # Green
"<c3=66ffcc,c9d1d1>", # Cyan
"<c3=ffccdc,d1c9d0>", # Magenta
"<c3=dddd00,eeeece>", # Yellow
"<c3=878787,d1d1d1>", # Grey
"<c3=f8f8f8,b8b8b8>" # White


But it keeps displaying the old colors.
Is there some part I am missing for color editing?
Thank you :)

Yeah, \b and \r set their colours in a different spot. If you search for \\[Bb], the first result, with the <c2=6546675A>, is the place you need to do the last of the edits.
