What problem does it solve? Procedural shaders often rely on arbitrary hard-coded RGB values that produce flat, unrealistic visuals. This Skill replaces guesswork with mathematically derived color systems, ensuring every hue emerges from equations, lighting, atmosphere, and energy models. ## Core Features & Use Cases - Procedural Palette Generation: Builds cosine palettes, OKLab gradients, blackbody radiation curves, and spectral approximations instead of hard-coded color ramps. - Physically Grounded Rendering Pipeline: Enforces a strict order from palette through lighting, atmospheric absorption, emission, HDR composition, tone mapping, and gamma correction. - Audio-Reactive Color: Maps bass, treble, midrange, and rhythm to hue transitions, saturation, and brightness modulation for music-driven visuals. - Use Case: When writing a GLSL ES 3.0 fragment shader for an audio-reactive nebula scene, use this Skill to derive a blackbody-based star palette, apply volumetric colored fog, and finish with ACES tone mapping and gamma correction. ## Quick Start Ask the agent to design a mathematically derived color palette and HDR tone mapping pipeline for your GLSL shader scene.
