About dark red
Pure red at 55 percent intensity and nothing else, which is why it reads heavy rather than rich. One of the few reds dark enough for body text on white, where it reaches 10 to 1.

Shades, tints and tones
Every step is generated from #8B0000. Click a swatch to copy its hex.
Shades of dark red
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 dark red
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 dark red
A tone is the base color with gray mixed in. Tones lose the shout without losing the hue, and they are usually what separates a considered palette from a loud one.
The dark red scale
The same color as the 50 to 950 ladder every CSS framework uses, with #8B0000 at 500. Click a step to copy its hex, or take the whole scale as variables for a design system.
Color schemes built on dark red
Harmonies are positions on the color wheel rather than matters of taste, which is why they keep working across very different designs.
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.
Colors close to #8B0000
Near neighbors, for when this color is almost right. Each one shifts hue, saturation or lightness by a small step.

Contrast and readability
Whether dark red works as text, and what to put on top of it when it is the background. Ratios follow WCAG 2.1, where 4.5 is the bar for body text and 3 for large text.

Used the other way round, #8B0000 as a background takes #FFFFFF text. That is the higher-contrast of the two, and it is what the tool picks automatically for any chrome sitting on your color.
Dark red reads better on a white 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.
