HEX, RGB, and HSL
HEX is a six-digit code like #3366FF. RGB lists the red, green, and blue channels from 0 to 255. HSL gives hue (0 to 360 degrees), saturation, and lightness as percentages. The tool shows all three for the color you pick, plus a contrast reading based on the WCAG relative-luminance formula so you can judge readability.
| Color | HEX | RGB |
|---|---|---|
| White | #FFFFFF | rgb(255, 255, 255) |
| Black | #000000 | rgb(0, 0, 0) |
| Red | #FF0000 | rgb(255, 0, 0) |
| Green | #00FF00 | rgb(0, 255, 0) |
| Blue | #0000FF | rgb(0, 0, 255) |
