HEX for CSS

HEX values like 2F6FED compactly represent red, green, and blue components in base 16. They are the default in stylesheets, design tools, and many APIs. Three-digit shorthand works only when each pair doubles identical digits, so full six-digit form is safer for accuracy.

Understanding RGB and HSL

RGB describes colors by light mix and maps closely to screens. HSL expresses hue, saturation, and lightness, which is far more intuitive when tuning variants: adjust lightness for hover states or reduce saturation for muted backgrounds without guessing each channel.

• HEX for stylesheets and tokens
• RGB for screen-oriented specifications
• HSL for building accessible shades and tints

Building a Consistent Palette

Pick a primary brand color, then generate lighter and darker steps in HSL by shifting lightness while holding hue steady. Document each step with its HEX value so future components match. Consistent ramps prevent every team member from inventing their own near-identical blues. Document hex values in a shared token file so designers and developers reference the same approved steps instead of sampling screenshots.

Developers can paste HEX values straight into stylesheets, while designers export RGB triplets for design tool inputs without manual conversion errors between color spaces.

Contrast and Accessibility

Body text needs strong contrast against its background; aim for ratios that satisfy WCAG AA at minimum. Large display text has slightly more leeway. Always test your chosen pair, since two attractive mid-tone colors can fail contrast even when they look harmonious together on a mood board.

Practical Workflow

Sample a starting color, refine it in HSL, copy the HEX into your code, and verify on both light and dark interfaces if you support them. Everything runs locally, so palette explorations for confidential rebrands never leave your browser. Revisit and refine tokens each quarter as the brand evolves, updating the shared documentation in the same pass.
