RichBlack
#004040
The color of the day is one named color from the library, featured for a whole calendar day — chosen from the date itself, so the same day always shows the same color. The card above carries its HEX, RGB and HSL values, and the featured color has a full page behind it with tints, shades, harmonies, contrast and matching palettes, which makes it a ready-made daily prompt for a design, a drawing or a CSS exercise.

Good to know
- The pick is derived from your own local date rather than a server clock, so two visitors on the same date see the same color.
- The featured color is always one of the named library colors, which is why its shades, harmonies and palette pages already exist.
- Palette of the Day uses the same base color and builds a five-color harmonious scheme from it, so the two daily pages agree.
- Every value on this page — HEX, RGB and HSL — copies with one click.
