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.

"WebbSaturation defines the brilliance and intensity of a color. When a pigment hue is “toned,” both white and black (grey) are added to the color to reduce the color’s saturation. In terms of the “additive” light color model, though, saturation works on a scale based on how much or how little other hues are represented in the color.

What Is the Difference Between the Terms Color Intensity and …

WebbLight of any given combination of hue and saturation can have a variable brightness (also called intensity, lightness, or value), which depends on the total amount of light energy present. Lightness of a color is changed by varying the intensity of all three primary colors by the same amount. WebbSaturation describes the vividness/dullness of a perceived color and, like lightness, can be measured independently of hue. Among the most widely used color spaces for defining and mathematically expressing these attributes are the CIE’s Yxy color space, established in 1931; the 1976 L*a*b* color space; and the L*C*h color space.

WebbThe CIELAB space is three-dimensional and covers the entire gamut (range) of human color perception. It is based on the opponent color model of human vision, where red and green form an opponent pair and blue … WebbReducing the saturation level of any pure hue to 0% results in a 50%-gray and a 50% value in luminance respectively. So for hues with natural luminance above 50%, luminance decreases when the saturation level decreases. For hues with natural luminance below 50%, luminance increases when the saturation level decreases. HSL 空间的局限

WebbIn cooperation with the Visual Experiences department of Philips Research, I studied the effects of coloured light on atmosphere perception. During my study, I gained knowledge on conducting and reporting a scientific research and expanded this experience in the field of perception, lighting, colours, emotions and atmosphere. WebbThe Perception of Colour, Part 2: Hue and Saturation. 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. However, colour is still useful in a number of contexts, and data visualization is one of them.

WebbThis property of being more vivid or more faded is termed saturation. The greater the portion of light that arrive at our eyes with wavelengths of the dominant hue, the deeper, more vivid, and thus more saturated, the color. The third color property used in this system is brightness, and it is one of the odder qualities of color. 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-
