WebbHue is a more technical definition of our color perception which can be used to communicate color ideas. Hue ranges from 0° to 359° when measured in degrees. Hues are basic colors we learn to connect with words as children. Hues can refer to the set of "pure" colors within a color space. Tint. Tint is a color term commonly used by painters. 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.
