Between luminance and colour, luminance is vastly more important to our everyday lives than colour is, because it helps us understand our 3D world in a way that colour doesn’t.

WebbColourfulness - the absolute colour intensity of a light stimulus - is a function of brightness and saturation. Brightness is the perceptual correlative of the psychophysical parameter of luminance, which in turn is the amount of radiant energy ( radiance) weighted according to the relative sensitivity of human vision to each wavelength. WebbHue is the perceptual attribute associated with elementary color names. Hue enables us to identify basic colors, such as blue, green, yellow, red and purple. People with normal color vision report that hues follow a natural sequence based on their similarity to one another.

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.

WebbIt exists across the hue circle, but, as we have seen, it also exists as an afterimage of that color. While the compli-ment of a color appears as the color’s opposite, they also exert a kind of balance. The pairs of colors and compliments in the hue circle have very different effects. Note the variations of value, saturation and temperature con- WebbThe unexpected difference between light perception and sound perception clarifies this curious aspect of colour. When beams of light of different colours, such as red and yellow, are projected together onto a white surface in equal amounts, the resulting perception of the eye signals a single colour (in this case, orange) to the brain, a signal that may be …

WebbSaturation describes how a color transitions from its most vivid appearance towards a grey appearance. A highly saturated color is a vivid, pure hue. As we desaturate the color, it becomes less saturated and starts to appear gray and washed out. Tint. As the vivid color moves towards white, we have tint. It’s the opposite of shade.
