Contrast Checkers

Some users require low luminance (lower brightness) in order to read the text on a webpage, while others have an easier time with brightly colored text on a dark background.

Given the diversity of visual preferences, it is recommended that webpages are designed with the proper contrast ratio so that information remains visible when visitors use the color adjustment tools built into popular browsers according to their unique needs.

There are a variety of online tools available for testing the contrast of both individual images and entire webpages. Some require that you enter the hex code of a given color combination to test the contrast, while others can scan pages based on the URL alone.
