What this tool does

Mix any two colors and predict the exact result. Type or pick two HEX values, drag the ratio slider from 0% to 100%, and watch the blended color update live in HEX, RGB, HSL, and LAB. Switch the blending color space to control how the transition feels: RGB (fast linear math, the default in most CSS and Canvas APIs — but can muddy mid-tones); HSL (rotates hue smoothly, ideal for tints and shades inside a single hue family); LAB (perceptually uniform, the color-science standard used in print, Photoshop's "Blend If", and modern design systems — equal numeric steps look equally spaced to the human eye). Beyond a single mix, generate a 5, 9, or 11-step gradient between the two endpoints — drop it straight into a design-system token sheet, a Tailwind palette, or a CSS `linear-gradient()`. Quick ratio presets (25 / 50 / 75) give you tertiary tints in one click. One-click copy on every output (HEX, RGB, HSL, LAB, full gradient array). 100% client-side: your colors never leave the browser, no account, no upload, no tracking.

How Color Mixer fits into your work

Use it while choosing, checking, converting, or documenting colors for real interface work.

Color jobs

  • Moving from a visual idea to reusable color values.
  • Checking contrast and accessibility before a UI ships.
  • Keeping brand, design, and implementation color decisions aligned.

Color checks

  • Verify contrast against the actual background, not just a sample swatch.
  • Check dark and light themes separately when both exist.
  • Copy the final format your design system or codebase expects.

Real-world use cases

  • Blend two brand colors for a co-branded landing page

    A partner campaign pairs your brand blue #2563EB with their orange #F97316. Marketing wants a single "joint" accent for buttons and the hero badge. Mix at 50% in LAB to avoid the muddy gray that RGB gives at the midpoint, then copy the HEX straight into the button token. Two values in, one shippable accent out, no eyeballing in Figma.

  • Generate a 9-step tint ramp for a design-system token sheet

    You have a base #0EA5E9 and need slate-50 through slate-900 style steps for your tokens file. Set the endpoints to near-white and near-black versions of the hue, generate the 9-step ramp in LAB so each perceived step is even, and paste the HEX array into tailwind.config.js. What used to be 9 hand-tuned guesses becomes one copy.

  • Find the exact halfway color between an old and new accent

    A rebrand moves the accent from #DB2777 to #7C3AED over two releases, and the PM wants a transitional shade for the in-between sprint. Drop both HEX values in, pull the ratio to 50%, and read the result in HEX and HSL. You ship a defensible midpoint instead of arguing over three similar pinks in Slack.

  • Teach why RGB and LAB midpoints differ in a color lesson

    A design student needs to show classmates why mixing #000000 and #FFFFFF at 50% gives #808080 in RGB but roughly #777777 in LAB. Switch the color space toggle live, screenshot both midpoint swatches side by side, and the gamma-vs-perceptual difference becomes a 20-second demo instead of a wall of math.

Common pitfalls

  • Using RGB to mix two saturated hues and getting a gray midpoint. Blue

  • Building a token ramp in RGB and wondering why mid-steps look crowded. Equal RGB steps are not equal to the eye because sRGB is gamma-encoded. Generate the 5/9/11-step ramp in LAB so perceived spacing is even.

  • Treating the screen HEX as a print-ready color. A monitor sRGB value does not map 1:1 to CMYK ink. Use the mixed HEX as a target and let the print shop's ICC profile do the conversion.

Privacy

Color mixing runs entirely in your browser. The two HEX values you type, the ratio, the chosen color space, and every output (HEX, RGB, HSL, LAB, and the full gradient array) are computed client-side and never sent to a server. To make sharing easy, your two colors and settings are encoded into the page URL, so a link reproduces your exact mix. Since colors are not secret, this is safe; just know the values live in the URL if you bookmark or share it. No account, no upload, no tracking.
