Webb25 juni 2016 · In terms of decreasing frequency of ‘nearer’ judgments the hue order was red, green, blue. When the two hemifields differed only in saturation, the perceived depth increased with increasing saturation difference, and whether the more saturated or the less saturated side was judged nearer depended on hue. WebbUsing only the Hue component makes the algorithm less sensitive (if not invariant) to lighting variations. Another popular option is LAB color space, where the AB channels represent the color and euclidean distances in AB space better match the human perception of color.

Effects of hue, saturation, and brightness on preference

"WebbNo, and here's why: The grayscale effect of non-color film is a result of altered perception. The film only responds to light amplitude, not wavelength. But our eyes don't work that way. Objects in a room reflect and absorb different parts of the visible light spectrum, based on the materials they are composed of. " - The perception of light hue and saturation

It involves the eye, but also the mind. Whether side-by-side or from afar, memory is a factor that affects our ability to see, describe, and match colors.
