Abstract: Basing on the feature that the color code could be redesigned, it explores the method
reducing the saturation of color code which is helpful to designers’ redesigning. Designers can
transfer color code into visual patterns; while during the redesign process, the color code’s
recognition mode and color limit become designer's restrictions. According to the pattern of
recognizing of color code, it discusses the problems during redesigning; on the basis of spatial color
mixing, it proposes the method of “alternate recognizing”, and tests the feasibility through two
experiments. In accordance with the analysis of experiment results, the “alternate recognizing” does
not lower the recognition of color code and reduces the saturation of color code at the same time; and
then it is beneficial to redesign the color code for designers.

Key words: color code, redesign, saturation, spatial color mixing
