Anti-aliased text in color
Over the past few years I've been fascinated to see the progress in making text look better on the screen. (I should confess right away that I know nothing about typography, and almost nothing about text anti-aliasing.) I recall reading some time ago that the Microsoft ClearType technology made use of color pixels, even when displaying "black" or gray text text.
