My hunch is that this could be the result of subpixel antialiasing. It often creates a sort of fringing around the text, which ideally isn't very apparent... but it takes advantage of separate RGB components. Red text has only one component, so the fringing may have the effect of darkening on one side, and brightening on the other, which can look a little like 3d relief.
