Harmonious neighbours on the wheel
Enter a base colour and this tool finds its analogous colours — the hues sitting either side of it on the colour wheel — holding saturation and lightness so they share the same mood. Adjust the angle slider to control how far apart the neighbours sit, from subtle to varied.
Analogous schemes are the go-to for calm, coordinated designs. Click any swatch to copy its hex. Everything runs in your browser with nothing uploaded.
