Developmental color perception.

The purpose of this research is to extend the investigation of surface color perception to several age levels. The 108-item color perception test, originally used with young children, employs six Munsell hue matrices divided into nine combinations each of low, mid, and high chroma and low, mid, and high value across two levels of hue difficulty. The pattern of error results are the same across the age groups comprising kindergartners, fifth graders, high school sophomores, nonartist adults, and professional artists: the lower the chroma and value, the higher the error rate; the higher the chroma and value, the lower the error rate. In hues, green and red are most difficult; orange and yellow are easiest. The frequency of error is linear with respect to age: the younger the group, the higher the error. The latency data differ with respect to age: adults are slowest, followed by kindergartners and fifth graders. High school sophomores are the fastest. The remaining latency results parallel the error results: the lower the chroma and value, the longer the latency and the more difficult the hue, the longer the latency. A set of surface color perception rules are generated.
