About this color
Red in CSS and design
Red is a medium, vivid color from the red family. Red is one of the 16 basic color keywords, which go back to HTML 4, long before CSS had 148 named colors.
Use it in CSS by name or by any of its codes; these all give the same color:
color: red;
color: #FF0000;
color: rgb(255 0 0);
color: hsl(0 100% 50%);For text on red, black reads best. Check other combinations with the contrast checker, or browse all CSS color names.
