About #660000

The precise color #660000 is an excellent choice for modern design projects. It is closely associated with the named CSS color Maroon. This translates to an RGB value of rgb(102, 0, 0).

While screens use RGB, printing presses rely on Cyan, Magenta, Yellow, and Key (black). The color uses 0% Cyan, 100% Magenta, 100% Yellow, and 60% Black. Always request a physical proof before doing a large print run with this exact code.

Web Content Accessibility Guidelines (WCAG) dictate how we should use this color. Mathematical luminance calculations suggest that #FFFFFF text provides the most optimal reading experience. Strict adherence to these ratios protects visually impaired users from unreadable interfaces.
