How This Color Mixer Works
Pick two starting colors, drag the ratio slider, and this color mixer online blends them using linear RGB interpolation, updating instantly as you move it. Whether you want to blend colors online quickly or fine-tune an exact midtone, at 0% you see the first color, at 100% the second, and everywhere in between is a proportional blend, exactly the mix two colors workflow a color blender exists to shortcut. Every calculation runs in your browser.
Reading the Gradient and Harmony Swatches
Below the mixed result, a 5-step gradient shows the blend at even intervals between your two starting colors, useful as a quick color gradient generator preview before committing to a full CSS gradient elsewhere. Alongside it, complementary and analogous harmony swatches are generated from Color A, so changing your first starting color reshapes the whole harmony palette, while the ratio slider only affects the mixed result and gradient.
Complementary vs Analogous: Which Should You Use?
A complementary color generator finds the hue directly opposite Color A on the color wheel, 180 degrees away, producing high-contrast pairings good for calls-to-action, accents, and anything that needs to stand out. An analogous color generator instead picks hues adjacent to Color A, roughly 30 degrees apart, producing harmonious, low-contrast palettes suited to backgrounds, gradients, and anything that should feel cohesive rather than loud. Neither is objectively better: complementary for contrast and emphasis, analogous for calm and cohesion.
Common Uses
Finding a midpoint color between a brand's two primary colors, previewing what a CSS gradient between two colors will actually look like before writing it, and generating a quick accent palette from a single starting color are the most common reasons developers and designers reach for this color mixing tool. It also works well as a hex color mixer for picking UI states, a hover color sitting partway between a base and an accent, for example, without eyeballing the blend by hand.
