Use the native colour picker, paste a HEX value, or tweak R/G/B/A inputs. Every other format (RGB, HSL, RGBA, HSLA) updates instantly.

FAQ
Color Converter — Frequently Asked Questions
Everything you need to know before you start.
Which colour formats does this tool support?
HEX (3, 4, 6, 8 digit), RGB, RGBA, HSL, HSLA, and a CSS variable snippet. Edit any field and the others update instantly.
How does the alpha channel work in HEX?
8-digit HEX adds two extra hex characters at the end representing alpha (00 = fully transparent, FF = fully opaque). For example, #3B82F680 is the standard blue at 50% opacity.
Why does HSL hue go from 0–360?
Hue is measured as a position on the colour wheel in degrees. 0° is red, 120° is green, 240° is blue, and the wheel wraps back to red at 360°.
Is my colour data stored anywhere?
No. The converter runs entirely in your browser. Nothing is uploaded.
