Overview
Introduction
This tool blends two hex colors together at any ratio you choose, entirely in your browser.
It's the tool to reach for whenever you need a precise, weighted blend between exactly two colors rather than a simple even mix.
What Is Color Blender?
A pure color-math tool that linearly interpolates between two hex colors, channel by channel, based on a ratio from 0 to 100.
It also generates a small solid-color swatch image so you can preview and download the exact blended color as a real PNG.
How Color Blender Works
Both hex colors are converted to RGB. For each channel, the tool computes colorA + (colorB - colorA) * (ratio / 100), which is standard linear interpolation, and rounds the result to a whole byte value.
The blended RGB is formatted into a hex code and also written into a 1x1 swatch image for visual preview and download.
When To Use Color Blender
Use it to find an exact midpoint or weighted blend between two brand colors, to compute a specific step along a gradient, or to generate a tinted or shaded variant of a color by blending it toward white or black.
It's especially useful when you need a precise, repeatable ratio rather than eyeballing a blend visually.
Often used alongside Color Mixer, Paint Colors Simulator and Color Sorter.
Features
Advantages
- Precise, adjustable weighting between exactly two colors, unlike an equal-weight average.
- The same well-understood linear interpolation math used by CSS gradients.
- Runs entirely client-side; nothing you enter is sent anywhere.
Limitations
- It only blends two colors at a time; for more than two, use the Color Mixer or run this tool in stages.
- Linear RGB interpolation doesn't always look perceptually even — a 50% blend can look closer to one color than the other depending on the two hues involved.
Examples
Best Practices & Notes
Best Practices
- Use ratio 50 for a true even blend, and smaller or larger values to lean the result toward one color or the other.
- Blend a color toward #ffffff or #000000 to generate quick, consistent tint or shade variants.
Developer Notes
The linear interpolation is a pure function with no DOM dependency, computing each channel independently with the standard a + (b - a) * t formula; the swatch reuses the shared createPixelBuffer helper from the pixel-buffer module.
Color Blender Use Cases
- Computing a precise midpoint or weighted blend between two brand colors
- Generating a specific step along a two-color gradient
- Creating consistent tint or shade variants by blending toward white or black
Common Mistakes
- Expecting a 50% blend to look perceptually halfway between two very different hues — linear RGB interpolation doesn't always match visual perception.
- Using this when more than two colors need to be combined — the Color Mixer handles that case instead.
Tips
- Blend any color toward #ffffff at a low ratio to create a quick tint, or toward #000000 for a quick shade.
- Step the ratio in increments of 10 or 25 to generate a full gradient ramp between two colors.
