A cinematography/design color-balance rule: compose a scene's palette as 60% dominant color, 30% secondary color, and 10% accent color. Higgsfield AI's production team calls it "the most visually appealing split" and applies it directly when prompting for image or video color — e.g., a forest scene composed as 60% green/blue, 30% red, 10% white.
Distinct from Color Transfer / Palette Locking, which matches an existing palette across shots for consistency; this rule instead governs how to compose a palette from scratch for a single scene, and pairs naturally with "Cinematic" Decomposed into Camera/Lens Parameters as another way of replacing vague quality adjectives with a concrete, specifiable parameter.
