What would sort of make sense would be classes like "wrong", "no" or "decrease", which would all have the same red color, but would mean different things. But now we're heading for unnecessary obstacles to editors...
Yes. Agreed. I just picked an arbitrary class name here. The only point I was trying to make is moving inline styles to a class gives us more consistency. If the color red means 'wrong' we should call the class wrong. I wasn't for one minute suggesting we should introduce classes for every specific color.. that would just be stupid :P
