How these are matched

Each of the 475 sites in the design library is compared with OpenAI on five things you see at a glance. Background: light or dark, and how close the shade is. Accent: the hue of the color on buttons and links. Font: the same family for headings and body, or one of them. Corners: the typical radius and pill buttons. Headlines: the largest type size and its weight. Same counts most, close counts half. Open any site for its fonts, color codes and a prompt for Claude Code, Cursor, Lovable or v0.
