About this color
Cyan in CSS and design
Cyan is a medium, vivid color from the cyan family. Cyan is one of the extended color keywords CSS adopted from the X11 color names. Its other name, aqua, is one of the 16 basic color keywords from HTML 4.
Cyan and aqua are two names for the same color in CSS: both mean #00FFFF.
Use it in CSS by name or by any of its codes; these all give the same color:
color: cyan;
color: #00FFFF;
color: rgb(0 255 255);
color: hsl(180 100% 50%);For text on cyan, black reads best. Check other combinations with the contrast checker, or browse all CSS color names.
