About sea green
A CSS keyword. Green with enough blue to feel cool without crossing into teal, and dark enough to hold white text.
Shades, tints and tones
Every step is generated from #2E8B57. Click a swatch to copy its hex.
Shades of sea green
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 sea green
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 sea green
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 sea green scale

Color schemes built on sea green
Harmonies are positions on the color wheel rather than matters of taste, which is why they keep working across very different designs.
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, #2E8B57 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.
Sea green 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.
