TESTING OF UNIFORM COLOUR SPACE USING CORRESPONDING COLOURS UNDER DIFFERENT ILLUMINANTS

摘要

Corresponding colours under various types of light sources including white LEDs were measured to test which uniform colour space could be appropriate to asses colour rendering index. It was suggested that the CAM02-UCS would predict colour appearance well compared with the CIELAB and the CIECAM02, while the adoption of colour space concerned with colour difference would affect the value of colour rendering index very little. So far, we could not reach the conclusion which of colour spaces is better for calculation of colour rendering index. We might need further examination of the adoption of uniform colour space.
