What is Luminance Contrast Ratio?

Luminance contrast ratio is a measure of the difference in luminance between two areas, typically used to assess the readability or visibility of text and images on a screen or other display. A higher contrast ratio indicates a greater difference between the bright and dark areas, making it easier to distinguish between them. This is particularly important in design and accessibility, as sufficient contrast ensures that content is readable for users with visual impairments.
