About copper

The color of the polished metal before it oxidises. Left alone it turns green, which is why the Statue of Liberty is the color it is rather than the color it started.

Color schemes built on copper

Harmonies are positions on the color wheel rather than matters of taste, which is why they keep working across very different designs.

Complementary

Two colors from opposite sides of the wheel. They make each other look more vivid, which is why the pairing is used for anything that needs to stand out.

Analogous

Three neighbours on the wheel. Nothing competes, so the result reads calm and settled, closer to how colour behaves in nature.

Split complementary

The base plus the two colors either side of its complement. It keeps most of the contrast while being much easier to balance.

Triadic

Three colors spaced evenly around the wheel. Strong and lively, and usually best with one dominant color and two accents.

Tetradic

Two complementary pairs, forming a rectangle on the wheel. The richest scheme available, and the hardest to keep from shouting.

Monochromatic

One hue at different lightness levels. Effortlessly cohesive, and the safest way to build a palette around a brand color.

Used the other way round, #B87333 as a background takes #000000 text. That is the higher-contrast of the two, and it is what the tool picks automatically for any chrome sitting on your color.

Copper reads better on a black background of the two. Contrast is a property of the pair, not of one color, so a color that fails here can still be perfectly usable against a different partner.
