Eight observers estimated chromaticness for central‐field colors of different chromaticity and constant luminance in a surround of the chromaticity of D 65 . The perceived chromaticness was scaled relatively and absolutely. The experimental results are compared with chromaticness as defined in different color spaces. In the CIELUV, CIELAB, LABHNU, and LABHNU2 spaces, colors of equal visual chromaticness are located approximately on circles. The LABHNU and LABHNU2 color spaces seem to describe the relative and absolute scalings in the best way for all observers.
