Color Mixer is a free browser-based tool that blends two colors together and shows the resulting mixed color in HEX, RGB, and HSL formats. Users pick two input colors and adjust the mix ratio to control how much of each color contributes to the result. The mixed color updates in real time with a visual preview alongside the two source colors. This is useful for finding intermediate colors between two given hues, exploring color transitions in a gradient, creating custom tints and shades by mixing with white or black, or experimenting with color combinations before committing to a palette. The tool performs RGB-space linear interpolation between the two colors, which is the same approach used by CSS color-mix() and most design tool blend operations. It runs entirely in the browser with no server communication. No account or installation is required. For complete results, Color Converter can convert between HEX, RGB, HSL, and HSV color formats, CSS Gradient Generator can generate CSS linear and radial gradients, and Tint & Shade Generator can generate lighter tints and darker shades of any color.
Color Mixer is most useful when a needed color sits between two known reference colors and needs to be identified precisely. A common scenario is having a brand's primary and secondary colors defined but needing an intermediate color for a hover state, a disabled variant, or a chart series that should feel visually between the two. Rather than estimating the intermediate hue by eye, Color Mixer computes it mathematically and provides the exact HEX code. Mixing a color with white produces tints (lighter versions), and mixing with black produces shades (darker versions), which is an alternative to using Tint and Shade Generator when the target lightness needs to be found relative to a specific dark or light reference rather than a percentage scale. The mix ratio slider lets users explore the full spectrum between the two input colors, making it easy to find the exact proportion that achieves the desired result. The RGB linear interpolation method used by Color Mixer produces perceptually even transitions for most color pairs, though for transitions across very different hues, the midpoint may pass through a gray or muddy intermediate. In these cases, mixing in HSL space sometimes produces more vibrant transitions, and the HSL output values can be adjusted manually in Color Converter to explore alternative approaches. The tool runs free in the browser without installation.
