The usage share of browser color depth is the proportion, often expressed as a percentage, of users of all web browsers who use that color depth. This figure can only be estimated, typically by determining the proportion of visitors to a group of websites that use a particular web browser. Browser color depth varies from place to place as well as through time.
Most modern browsers display in true color.
