In the typography (plate29.B) certain color words appears in front compare to other color words. Even though all of them are on the same 2D surface plane the illusionistic appearance of words receding back or coming in front is due to the combination of colors. Thus it creates color dimension due to illusion.

The above color illusions (plate30 A&B) created psychedelic effect due to our perception. Parallel lines become angular (plate 20B) while the spiral effect (plate30 A) creates strange visual effect.
