Duotone Color Palette Generator
Used by developers, writers, and creators worldwide.
A duotone color palette generator builds striking two-color schemes that blend a dark shade into a light one across a smooth ramp. Duotone is the look behind countless modern posters, album covers, and photo treatments — two colors mapped onto shadows and highlights for an image that feels bold and contemporary. This tool picks two well-separated hues and interpolates between them, giving you a ready ramp of steps to use as a gradient, a photo duotone, or a compact palette. Choose how many steps you want and generate a fresh combination. It is ideal for photo filters, hero sections, posters, and trendy brand visuals. Duotone works best with high contrast between the two colors, so the effect reads clearly, and it pairs beautifully with high-contrast black-and-white photography. Generate several and keep the duo whose mood — calm, energetic, moody, or vivid — matches the feeling you want.

FAQ
what is a duotone
A duotone is an image or design built from just two colors, typically one mapped to the shadows and one to the highlights, with a smooth blend between. It produces a bold, stylish look popular in posters, album art, and modern web design.
what colors work best for duotone
Two colors with strong contrast in lightness, and often a noticeable difference in hue, read most clearly. A dark, saturated shade paired with a bright one gives the punchy, high-impact effect that makes duotone distinctive.
how do i apply a duotone to a photo
Most image editors offer a duotone or gradient-map adjustment: convert the photo to grayscale, then map the dark tones to one color and the light tones to the other. The ramp from this tool gives you the two endpoints and the steps between.
