How It Works

1

Pick or type a color

Use the color picker, or type a HEX, RGB or HSL value directly.

2

See every format at once

HEX, RGB, HSL and HSB update together, live, with a preview swatch.

3

Copy what you need

One click copies any format, ready to paste into CSS, design tools, or code.

Privacy note: all color parsing and math runs locally in plain JavaScript. Nothing you type ever leaves your browser.

Common Uses

CSS development

Convert a design tool's HSL value into the HEX your CSS already uses, or vice versa.

Design handoff

Translate a designer's color spec into whatever format a codebase expects.

Picking a matching shade

Use HSB to nudge brightness or saturation while keeping the same hue.

Quick experimentation

Hit Random color to explore values and see every format for a color at once.

Frequently Asked Questions

What color formats does this tool support?

HEX (#rrggbb or #rgb shorthand), RGB, HSL and HSB/HSV. Type a value in any of these formats, or use the color picker, and every other format updates instantly.

What's the difference between HSL and HSB/HSV?

Both describe a color as hue plus two other components, but HSL uses lightness (0% is always black, 100% is always white) while HSB/HSV uses brightness/value (0% is always black, but 100% brightness with full saturation gives the purest, most vivid version of the hue). Designers often find HSB more intuitive for picking a vivid color; HSL is more common in CSS.

Does this tool store or upload the colors I enter?

No. All parsing and conversion happens locally in your browser using plain JavaScript math. Nothing is sent to a server, logged, or stored.

Can I paste a CSS color value directly?

Yes. Paste values like #2563EB, rgb(37, 99, 235), or hsl(220, 83%, 53%) into the input field and the tool will parse them automatically.
