Contrast Metrics Explained Luminance contrast is a perceptual measure that defines the difference between the perceived lightness of two colors. Contrast, more broadly, is a difference metric and can include differences in hue, but for this discussion, we will consider only the difference in perceived lightness.imply substitute NY min for Y max. in the equation. A 3:1 contrast ratio, for example, is equivalent to a 50% Michelson contrast. Michelson and Weber contrast will yield similar values if Y b is significantly less than Y f, but not otherwise.

Contrast (vision) Contrast is the difference in luminance or colour that makes an object (or its representation in an image or display) distinguishable.In visual perception of the real world, contrast is determined by the difference in the color and brightness of the object and other objects within the same field of view.ontrast sensitivity is a measure of the ability to discern between luminances of different levels in a static image. Contrast sensitivity varies between individuals, reaching a maximum at approximately 20 years of age, and at angular frequencies of about 2–5 cycles per degree.
