Color Stereopsis

If you are curious about the reason why some of the color text seems to be in front of the
the rest of the text, it has to do with Color Stereopsis. This effect was first reported
several decades ago but has only recently been explained. For a full explanation see M.
Dengler and W. Nitschke's paper titled "Color Stereopsis: A Model for Depth Reversals
Based on Border Contrasts" in the journal Perception and Psychophysics, Feb. 1993, vol.
53, no. 2, pages 150-156.
