Contrast (vision): Products, Contrast sensitivity & Biological contrast sensitivity

Contrast is the difference in luminance or color that makes an object (or its representation in an image or display) distinguishable from a background. Human vision is more sensitive to relative differences than to absolute luminance, so perceived appearance can remain fairly stable despite large changes in illumination.
