Abstract: The perception of brightness of unrelated self-luminous colored stimuli of the same luminance has been investigated.
The Helmholtz–Kohlrausch (H-K) effect, i.e., an increase in brightness perception due to an increase in
saturation, is clearly observed. This brightness perception is compared with the calculated brightness according to
six existing vision models, color appearance models, and models based on the concept of equivalent luminance.
Although these models included the H-K effect and half of them were developed to work with unrelated colors,
none of the models seemed to be able to fully predict the perceived brightness. A tentative solution to increase the
prediction accuracy of the color appearance model CAM97u, developed by Hunt, is presented.
