About cornflower blue

A mid blue at 219 degrees, and the most recognized keyword here for a reason unconnected to flowers: it was the default clear color in XNA and the DirectX samples, so a generation of developers met it as the color of an empty scene. At 3 to 1 on white it is large text only.

Color schemes built on cornflower blue

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 neighbors on the wheel. Nothing competes, so the result reads calm and settled, closer to how color 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, #6495ED 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.

Cornflower blue 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.
