How many colors do all browsers recognize?

All browsers universally recognize 16 colors that form part of the standard palette defined by the HTML color specification. This palette includes basic colors such as red, blue, green, yellow, and their variations. The significance of these 16 colors lies in their consistent representation across different web browsers and platforms, allowing developers to ensure a uniform appearance of web pages regardless of the user’s system configuration.

While many colors can be defined in web design using RGB or hex codes, especially with modern standards and styling methods, the foundational colors recognized by all browsers remain limited to this original palette. This ensures backward compatibility and aids in creating accessible designs.
