Color space
A color space is a defined coordinate system for representing colors using specified components, dimensions, or numerical values.
CSS in Depth, Second Edition
A color space is a coordinate system that represents colors with defined component dimensions and ranges.
- How it is used
- Guides CSS color selection and adjustment when implementing a design mockup.
- How deep it goes
- Defines color space against gamut and compares RGB and HSL arrangements, without deriving their coordinate mathematics.
- Examples
- Uses RGB and HSL diagrams, hexadecimal and rgb() values, and a gradient-backed button.
- What you can do after
- Apply it via CSS color notations to choose editable colors and account for browser support.

Everyday Data Visualization
A model for representing colors as coordinates or values in a defined set of color dimensions.
- How it is used
- Supports selecting and tuning visualization colors, especially palettes matched to data.
- How deep it goes
- Defines three-dimensional color coordinates and works through RGB and CIELAB axes without pursuing advanced color science mathematics.
- Examples
- Uses RGB cyan and purple triplets, CIELAB slices at L*=75 and L*=25, and sequential gradient comparisons.
- What you can do after
- Apply it via Figma by switching color spaces to select and tweak visualization colors.
