Color Mixer - Blend Colors Online

A color mixer is an online tool for combining two colors to create a new color. You can think of it as a digital version of mixing paint, except digital color mixing works with numerical color values and mathematical interpolation rather than physical pigments.

A typical color mixer starts with two source colors. You can enter their HEX values, choose a mixing ratio and generate the resulting color. For example, mixing a blue color with a red color can produce a purple family result, while mixing a strong color with white can create a lighter tint.

Modern web color tools can go further by allowing the interpolation color space to be selected. CSS's color-mix() function supports mixing colors in spaces including sRGB, HSL, Lab, OKLab and OKLCH. :chatgpt-content-reference{index="1"}

The mixing ratio controls how strongly each source color contributes to the result. If both colors are assigned equal percentages, each receives 50% of the mix. If Color A receives 80% and Color B receives 20%, the resulting color is much closer to Color A.

CSS color-mix() accepts optional percentages for each color. When both percentages are omitted, the colors are mixed equally. When only one percentage is specified, the other color is normalized to the remaining percentage. :chatgpt-content-reference{index="2"}

Color mixing is not always a simple matter of averaging three RGB numbers. Different color spaces represent color differently, so interpolating between the same two colors can produce different intermediate results.

The CSS color-mix() function lets developers specify an interpolation color space. Available spaces include sRGB, linear sRGB, Lab, OKLab, LCH and OKLCH, among others. :chatgpt-content-reference{index="3"}

MDN notes that the choice of interpolation space affects the result: Oklab and Lab are useful for perceptually even interpolation, while OKLCH can help maintain chroma during transitions. :chatgpt-content-reference{index="4"}

Modern CSS includes the color-mix() function, allowing developers to generate a mixed color directly in CSS. This is useful for design systems, hover states, component variations, gradients and theme colors. :chatgpt-content-reference{index="5"}

.button {
  background: color-mix(
    in oklab,
    #635BFF 70%,
    #06B6D4 30%
  );
}

You can also use the result as part of a design system instead of manually creating every intermediate shade. This can make color relationships easier to maintain as a project grows.

CSS color-mix() is widely available in modern browsers, although individual color spaces and advanced interpolation options can have different compatibility levels. :chatgpt-content-reference{index="6"}

A color mixer can be useful beyond producing one final color. By changing the ratio gradually, you can create a sequence of related shades between two colors. This can be useful for UI states, illustrations, backgrounds and design-system tokens.

For more controlled palette creation, you can combine mixing with BestColorPicker's Color Harmony Finder, Color Tint Generator and Color Difference Calculator .

Digital color mixing and physical paint mixing should not be treated as identical processes. Digital tools interpolate numerical color representations, while physical pigments interact through absorption, reflection and material properties.

A mixed color may look attractive but still provide poor readability when used with certain text or background colors. After creating a new color, check its contrast in the actual interface where it will appear.

Use the Color Contrast Checker for conventional contrast testing and the APCA Contrast Checker for an additional perceptual contrast workflow.
