- How it is used
- Supports inspecting applied CSS colors, converting notation, and selecting palette colors while previewing changes.

- Walks through DevTools controls and an OKLCH picker, including gamut boundaries; it does not develop color theory.
- Examples

Everyday Data Visualization
A color picker is an interface for selecting and adjusting a color and its representation in a color model.
- How it is used
- Refines categorical color palettes so unintended visual emphasis and confusing color similarities are reduced.
- How deep it goes
- Demonstrates switching color representations and adjusting saturation or lightness, without developing color-picker internals.
- Examples
- Uses a sunset palette, Coolors-generated colors, Figma adjustments, and comparisons of yellow, blue, tan, and magenta.
- What you can do after
- Apply it via a color picker to balance palette emphasis, distinguish colors, and inspect alternate color representations.
