The Accent button communicates strong emphasis and is reserved for actions that are essential to an experience. Don’t use more than 3 accent buttons in the same view.

The Default button is for medium emphasis. Use it in place of a call to action button when the action requires less prominence, or if there are multiple primary actions of the same importance in the same view.

The Subtle button is for low emphasis. It’s paired with other button types to surface less prominent actions, and should never be the only button in a group.
