Color Mixer

Mix two colors together at any ratio. Generate intermediate color steps for gradient palettes. View HEX, RGB, and HSL values.

What is Color Mixer?

A color mixer blends two colors together to create a new color. By adjusting the mix ratio, you control how much of each color contributes to the result. The Steps mode generates a series of evenly-spaced intermediate colors between your two picks -- perfect for creating gradient palettes, design systems, or color scales. All mixing is done in RGB color space with real-time preview.

How to Use Color Mixer

  1. 1

    Pick two colors

    Use the color pickers or type HEX values for Color 1 and Color 2. These are the two endpoints of your mix.

  2. 2

    Adjust the ratio

    Drag the mix ratio slider. At 0% you see pure Color 1, at 100% pure Color 2, and at 50% an equal blend. The gradient track shows the full spectrum between your colors.

  3. 3

    View the result

    The mixed color appears in the center with its HEX, RGB, and HSL values. Click the swatch to copy the HEX value.

  4. 4

    Generate gradient steps

    Click a step count (3, 5, 7, or 10) to generate evenly-spaced intermediate colors between your two picks. Each step swatch is clickable to copy its color.

Frequently Asked Questions

How does color mixing work?+
This tool uses RGB (additive) color mixing. Each color channel (Red, Green, Blue) is linearly interpolated between the two input values based on the mix ratio. At 50/50, each channel is the average of the two input values. This matches how CSS color-mix() works in the sRGB color space.
What is the difference between RGB mixing and paint mixing?+
Paint mixing is subtractive -- mixing red and blue paint gives purple. RGB mixing is additive -- mixing red and blue light gives magenta. This tool uses additive mixing, which matches how screens display color and how CSS gradients work.
How do I create a color palette from two colors?+
Select your two endpoint colors, then click a step count (5 or 7 recommended). The tool generates evenly-spaced colors between them. Copy each color's HEX value to build your palette. This is great for creating a monochromatic or two-tone design system.
Can I mix more than two colors?+
This tool mixes two colors at a time. To mix three or more colors, mix the first two, then use the result as Color 1 and your third color as Color 2. Repeat for additional colors.
What color space is used?+
Mixing is performed in sRGB (the standard web color space). For perceptually uniform mixing, LAB or OKLAB color spaces produce better results, but sRGB is the most widely used and matches CSS behavior.
Can I use the gradient steps as CSS colors?+
Yes. Each step outputs a standard HEX color value that works in any CSS property. Click a swatch to copy the HEX value. You can use these values to build a CSS gradient, design token scale, or custom color palette.
Why does 50/50 mix not always look like the midpoint?+
Human color perception is nonlinear. A mathematical 50/50 mix in sRGB may not appear visually centered to your eyes. For perceptually balanced midpoints, mixing in OKLAB or HCL color space is more accurate -- but sRGB is the industry default.
Can I save my palette?+
Currently you can copy individual HEX values. Use Ctrl+Shift+C (Copy All) to copy all step colors at once. Paste them into a CSS variables file or design tool for reuse.
