This is a mostly insignificant problem, but it's been bugging me for a while and I figured someone on here might be as ridiculously OCD as I am (this is a programmer community after all).
Basically, the problem is that TextMate doesn't seem to calibrate syntax highlighting colours, while Xcode does. What this means in practice is that, while I've faithfully recreated my TextMate theme in Xcode, the syntax highlighting in Xcode seems noticeably less vivid that it does in TextMate. If I use DigitalColor Meter to check the actual colours in Xcode, they don't match the values I entered, while in TextMate they do.
Any ideas what's going on here? Thanks!
