A color palette and a type scale are a good beginning. A design system becomes more useful when those foundations connect to the interface patterns a team builds every day.

Foundations give choices a shared language

Color roles explain how a palette is used. Typography rules show how headings, labels, and body text relate. Spacing values help screens feel measured instead of improvised.

A token names a design decision so teams can reuse it consistently.

Components turn rules into practice

Buttons, cards, and form fields put those decisions into repeatable pieces. The system stays useful when those pieces can adapt without losing their shared visual logic.
