About yellow

Red and green at full output with no blue. Close to the brightest thing a display can show short of white, which is why it is the standard colour for hazard markings.

Shades, tints and tones

Every step is generated from #FFFF00. Click a swatch to copy its hex.

Shades of yellow

A shade is the base color with black mixed in. Shades read as deeper and more dramatic, and they are what you reach for when a color needs to recede or carry weight.

Tints of yellow

A tint is the base color with white mixed in. Tints turn pastel as they lighten, which makes them useful for backgrounds and for anything that has to sit behind text.

Tones of yellow

A tone is the base color with grey mixed in. Tones lose the shout without losing the hue, and they are usually what separates a considered palette from a loud one.

The yellow scale

The same color as the 50 to 950 ladder every CSS framework uses, with #FFFF00 at 500. Click a step to copy its hex, or take the whole scale as variables for a design system.

Color schemes built on yellow

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.

Colors close to #FFFF00

Near neighbours, for when this color is almost right. Each one shifts hue, saturation or lightness by a small step.

Used the other way round, #FFFF00 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.

Yellow 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.
