I always forget what colors I\'m dealing with in CSS when I see it hex value. I would like to use the name instead (e.g color: lightgreen). Is it supported by all browsers?
Use classes then
This has the benefit you can refine your colors just by updating your CSS. Be aware though it isn't a great idea to name a class after how it appears, since you may want to change all your orange text to red and you'll end up with the class .lightorange {color:red}
which is just odd.
