How this service works
Mix two hex colors at a ratio in sRGB or in linear light (physically correct), returning the blended hex.
Output
Returns a JSON object containing the blended hex color (result), the two input hex colors (a, b), the color space used (space), the blend weight of color B (weightOfB), and a summary string. May also include a source, asOf timestamp, and optional disclaimer or reasons fields.
Example use cases
UI gradient midpoint computation
“I'm building a UI gradient between #1A1A2E and #E94560. Can you mix those two colors in sRGB at exactly 50/50 and give me the hex code for the midpoint stop?”
Physically correct color blending for data viz
“For a heatmap I need a perceptually correct blend of #00FF00 and #FF0000 using linear light, weighted 80% toward red. What hex color does that produce?”
Brand color tint generation
“Our brand blue is #003087 and white is #FFFFFF. What hex do I get if I mix them with 25% of the blue and 75% of the white in sRGB?”

Endpoint
GEThttps://color-design.x402tookit.com/color-mix?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a precise, single blended hex color from two inputs, especially when physical accuracy matters (linear light) or when you need a weighted mix rather than a simple average. Prefer the sibling gradient-steps endpoint if you need multiple interpolated colors across a range.
Side effects
- Invalid hex color format for a or b (missing #, wrong length) — likely 400 error or null result
- weight_b outside 0–1 range — may return error or undefined behavior
- Unknown color space string — defaults to sRGB or returns error
- Missing required query parameters a or b — returns error
- Network timeout or service unavailability — no result returned
