What Is a Color Mixer?
A color mixer online tool lets you combine two or more colors in precise proportions and instantly see the blended result in HEX and RGB. Instead of guessing how two brand colors will look when combined, you set each color's weight, choose a blending mode, and get an exact output you can copy straight into your code or design file.
How to Blend Colors Online
- Add your colors — use the picker or paste a HEX value. Add as many colors as you need.
- Set proportions — drag each color's weight slider to control how much it influences the final blend.
- Pick a mixing mode — choose sRGB (standard gamma-encoded), Linear RGB (physically accurate light mixing), or OKLab (perceptually uniform blending based on the OKLab color space).
- Copy or save — grab the resulting HEX or RGB value, export CSS variables, or save the mix for later.
Why Use This Color Blending Tool?
Most color blending tools only offer simple RGB averaging, which can produce muddy or desaturated results — especially with complementary hues. This tool gives you three distinct mixing algorithms so you can match the blending behavior to your project. OKLab mode, for example, keeps blends vibrant and perceptually even, making it ideal for design-system tokens and UI surfaces where subtle shifts matter.
Common use cases include finding the exact midpoint between two brand colors, creating tints by mixing with white (#FFFFFF) or shades by mixing with black (#000000), and dialing in subtle background tones without switching to a full design application. Once you have your blended color, check readability against text with the contrast checker or mix colors in HEX and RGB and then convert the result to HSL or CMYK using the color converter.
Mixing Modes Explained
sRGB (Gamma) blends the raw hex values — fast and predictable for everyday tasks. Linear RGB converts to linear light first, producing results that match how physical light actually combines; this avoids the darkened midpoints you often see in standard gradients. OKLab uses a perceptually uniform model developed to keep hue and saturation stable across the blend, following the principles described in the CSS Color Level 4 specification. If you need multi-stop transitions rather than a single blend, build them in the gradient generator.
Tips for Better Blends
Start with two colors at 50 % each to find the true midpoint, then shift the weight toward whichever hue should dominate. When creating a tint or shade scale, increase the white or black proportion in small steps — 10 % increments give you a smooth ramp without overshooting. To expand a single blended result into a full Tailwind-style token scale, pass it to the Tailwind scale generator and get a production-ready 50–900 ramp in seconds.
