What it does
ColorHexa is a free colour reference and conversion tool. A single search field accepts common colour notations and produces model values, related schemes and colour previews. The same field handles blends, subtraction and gradients.
The input can be a short or full hex code, RGB channels, HSL values or a colour name. The examples also cover Lab, LCH, XYZ and other numeric formats, with the expected ranges shown beside each syntax.
Use a plus sign to mix colours, adding percentages when the proportions matter. A query such as 70% dark blue + 30% orange produces one blended result. For a transition, separate two colours with the word to; the gradient tool presents RGB, HSV and reverse-HSV versions.
A colour-detail page brings the equivalents together. For #663399, it shows RGB 102, 51, 153 and the CSS form hsl(270,50%,40%), alongside related schemes, shades and tints.
Strengths
- The input syntax accepts multiple colour models and punctuation styles.
- Blends can specify the proportion contributed by each colour.
Watch out for
- The gradient tool uses two endpoints; multi-colour mixing is a separate operation.
Best for
- Designers comparing a known digital colour across formats and combinations.
