About this color

Yellow is a medium, vivid color from the yellow family. Yellow 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: yellow;
color: #FFFF00;
color: rgb(255 255 0);
color: hsl(60 100% 50%);For text on yellow, black reads best. Check other combinations with the contrast checker, or browse all CSS color names.
