Two experiments were designed to determine effective colors for stimulus lights as measured by speed of detection and accuracy of identification. In addition, the nature of the interactions between stimulus color, background color, and amount of ambient illumination was assessed. Responses to four stimulus lights (red, green, yellow, and white) were evaluated against four colored backgrounds (copper, tan, blue, and green) under two levels of ambient illumination. The overall ordering of stimulus colors as measured by speed of responding was, from fastest to slowest, red, green, yellow, and white. For errors in color naming, the order from least to most was green, red, white, and yellow. Detection and identification were more difficult under bright ambient illumination. The addition of an identification task added about 0.25 second to the response times for each color.
