Typography and Color

Color Contrast Tokens

A status panel defines foreground and background tokens, reads them into the component, and adds an accent color with readable contrast.

Program

Color decisions are easier to maintain when reusable tokens hold foreground, background, and accent values. Each token still needs enough contrast in the final UI.

  1. Define foreground and background tokens.

    The tokens are available on the panel.
    Custom properties can hold color choices for reuse.

  2. Apply the contrast pair.

    The panel reads its text and surface colors from tokens.
    Foreground and background need to be evaluated together.

  3. Add an accent border and spacing.

    A teal frame gives the message a clear edge.
    Accent color should reinforce state without carrying meaning alone.

  4. Color the important text with the accent.

    The status phrase now carries the accent color.
    Emphasis can use accent color while body text keeps high contrast.
contrast Contrast is the visible difference between foreground and background colors.
color token A color token is a named reusable color value.
