Blue and Teal color palette

Need two accents that read as related instead of competing? Blue #3B82F6 is brighter and more saturated, leaning slightly purple. Teal #0E7C86 is darker and more muted, with a green undercurrent. They sit 55 degrees apart on the wheel and share a cool mid-tone character, which puts the ratio at just 1.34 to 1.

That low contrast is the point. Use blue for primary buttons and active states in a Tailwind UI, then bring teal in for secondary actions, links, or chart series in the same family. Their blended midpoint is a mid blue (#2481BE), so gradients stay clean. Avoid stacking the two as text and background.

Why Blue and Teal blend best in OKLab

The same two colors blended three ways. This site uses OKLab, which keeps the blend smooth and evenly lit. The other two are shown so you can see what to avoid: sRGB darkens and muddies the middle, and HSL detours through colors that are not in your palette.

Do not place Blue text on Teal (or the reverse) for body copy. For readable text, pair a dark scale step such as blue-800 or teal-900 with a light one like teal-50.

Contrast pairing grid

Rows are Blue steps, columns are Teal steps. Each mark is a Blue step shown on a Teal step: a check means it clears WCAG AA for text (4.5:1). If you can read the mark, the pairing is legible.

How we name colors

There is no single official authority for naming colors. We use the common, widely recognized name as the primary label for each color (here, Blue and Teal); many common names are themselves W3C CSS named colors. For transparency we also show the nearest W3C CSS named color and the perceptual distance, ΔE, measured in OKLab. A small ΔE means the name is essentially exact; a larger one means it is the closest standard name rather than a perfect match.

Sources: W3C CSS Color Module Level 4 and the open color-name-list dataset, used to verify every color sits near a recognized name.
