Why it matters
Emphasis only works when it's rare. Highlight everything and nothing stands out.
Rules to follow
- Use the accent color for one element per view: the primary action or the recommended option.
- Never rely on color alone to make something stand out; add size, weight, position or a label.
- Keep motion for the one thing that needs attention, and respect reduced motion.
