## What it is
Mixbox is a color mixing library that treats RGB colors as real paint pigments using Kubelka & Munk theory, producing natural mixtures like yellow and blue making green. It offers a simple RGB-in, RGB-out interface with bindings for C++, C#, Java, JavaScript, Python, Rust, Unity, Godot, and shaders.

## Use cases
- mix colors like real paint in a digital painting app
- make yellow and blue blend into green instead of gray
- generate natural pigment-based color gradients
- add realistic paint mixing to a game engine brush tool
- implement pigment mixing in a GLSL or HLSL shader
- avoid muddy color mixtures in smudge brushes

## When to choose
- you need realistic paint-like color blending in painting or drawing software
- you want saturated gradients with natural hue shifts instead of RGB averaging
- you need bindings across many languages and engines including Unity, Godot, and shaders

## When to avoid
- you only need simple RGB or HSL interpolation without pigment realism
- your project requires a permissive open-source license (license is custom/restricted)
- you need full spectral color science beyond the built-in pigment set
