What color formats are supported?
HEX (#RRGGBB), RGB, RGBA, and HSL. You can input any format and see all others update in real-time.
Does it support 3-digit HEX?
Yes. #f0c is automatically expanded to #ff00cc. Output always shows the 6-digit form.
Can I pick a color from my screen?
Use the native color picker (click the colored square). In Chromium browsers it supports the EyeDropper API for screen picking.
Why does HSL look different?
HSL (Hue, Saturation, Lightness) is a perceptually different color model. Hue goes 0-360°, S and L are 0-100%. Same color, different coordinates.
