This skill should be used when the user asks to "build a color palette for a motion piece", "make a gradient background", "animate a color transition", "interpolate colors smoothly", "fix muddy/gray gradients", "convert colors to OKLCH", "color-grade a video for mood", "fix washed-out After Effects renders", "gamma shift", "Rec.709 vs sRGB", "colors shifted after rendering", or "match preview to final video". Covers palette construction, gradients, perceptual interpolation (OKLCH/Lab), grading order, and video/render color management.

Color in Motion

Choose, pair, and animate color for motion design: building restrained palettes, constructing gradients that read as premium, interpolating colors in perceptually-uniform spaces, and grading a piece for mood and consistency. Produces palettes with exact OKLCH/hex values, gradient CSS/code, and transition parameters.

When to use

  • Picking or pairing a palette for a motion or video piece.
  • Building gradient backgrounds (mesh, noise, animated drift).
  • Animating color transitions (button states, theme switch, loaders).
  • Grading a video for mood, or fixing dull/gray gradient interpolation.
  • Fixing washed-out, gamma-shifted, or platform-inconsistent After Effects renders, and choosing correct per-platform export/color tags.

Core techniques

1. Build a restrained palette

Limit hues. A strong motion palette is 1 primary + 1 accent + 2-3 neutrals. Derive contrast and depth from lightness and chroma, not from adding more hues. Extra hues fight for attention and read as amateur.

In dark scenes, make the accent pop with low-to-moderate chroma and high lightness rather than maximum saturation — a blown-out saturated accent vibrates and looks cheap on dark backgrounds.
