Indigo and Cyan color palette
indigo · 0
Indigo at #4B0082 reads as a deep, saturated purple that sits firmly in luxury territory. Pair it with cyan #06B6D4, a bright mid-tone blue, and you get a jump from dark to light with the two 87 degrees apart on the wheel. The ratio is 5.33 to 1, so cyan text on indigo passes AA for body copy.
This pairing reads well on the web, especially as a gradient. The blend runs through a muted blue-purple (#4F67AC) before reaching cyan, which keeps the transition smooth instead of muddy.
In Tailwind, the full 50-900 scales give you hover states, surfaces, and borders without leaving the palette.

Why Indigo and Cyan 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.
Accessibility
Indigo and Cyan can be used together as text and background.
Contrast pairing grid
Rows are Indigo steps, columns are Cyan steps. Each mark is a Indigo step shown on a Cyan 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, Indigo and Cyan); 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.
