Common Use Cases

Colour format conversion is a daily task for frontend developers and designers. CSS uses HEX and HSL, design tools like Figma use HSB, and JavaScript canvas operations use RGB. Being able to instantly convert between all these formats — and see the colour visually — removes the friction of working across different tools in a design-to-code workflow.

How to Use

  1. Enter a colour value in any format: HEX (#3b82f6), RGB (59, 130, 246), or HSL (217, 91%, 60%).
  2. The equivalent values in all other formats update instantly.
  3. Use the visual colour picker to pick a colour by eye and see all its format values at once.
  4. Click the Copy button next to any value to copy it in that format.

Frequently Asked Questions

What about RGBA or HSLA for transparency?

This tool converts opaque colour values. RGBA and HSLA add a fourth alpha channel for opacity (0-1). Take the RGB output and add an alpha value, e.g. rgba(65, 105, 225, 0.5) for 50% transparency.

Why do colors sometimes look different on different screens?

Colour appearance varies with screen calibration, colour profile, brightness, and ambient lighting. The colour codes are mathematically precise, but rendering depends on the display hardware.

What is the difference between HSL and HSB/HSV?

In HSL, 50% lightness is the pure colour and 100% is white. In HSB, 100% brightness is the pure colour. CSS uses HSL natively; Photoshop and many design tools use HSB.
