Process for coloring surfaces

摘要

The invention relates to a process for coloring surfaces in such a way that two juxtaposed colored areas cannot be visually perceived as distinct from one another unless their distance from the eye drops below a predetermined distance. The first area is colored by juxtapositioning unitary zones of at least two colors and the second area is colored by the resultant color of the optical mixture of the colors used for the first area. One important application of the invention is in display advertising.
