Turn one base color into a full color-theory palette — eight harmony rules, per-swatch HEX/RGB copy, and a live UI mockup that shows the scheme in action.
Loading tool…
Use the swatch, type a hex, click a quick pick, or hit Random for a tasteful surprise.
Tap one of the eight rules — each is labeled with its geometry, such as triadic at 120° apart or complementary at +180°.
Click a swatch for its hex, use the tiny buttons for HEX/RGB individually, or press Copy all for the full list.
The mockup panel shows the darkest, base and lightest colors working together as background, accent and text.
