Sorry, but I draw a line there. If I have to take any special action to be able to read someone's normal text (e.g. it's not being colored to intentionally mask it from other text) then I'm just not going to read it. Using colors in an unnecessary way can and does impact readability.(Have to highlight it to read it, but I do that anyways sometimes to avoid losing my place lol :x )
At any rate, there's some good posts on the topic in hand. It's good to see that most people agree that as long as it's a feature that's being added, the dev time spent to make it work shouldn't be wasted and it should be good for -something-.
