Swatchwell

Upload a logo and Swatchwell proposes a color system with accessible contrast pairs, two or three type pairings and a starter set of social, slide and email templates that use them. Every color comes with its contrast ratio against your backgrounds, and you can lock any element before regenerating the rest.

Freelance designers use it to get a first brand direction in front of a client quickly; small companies use it to stop using six slightly different blues. Exports include Figma styles, CSS variables and a PDF guide. It is a starting point, not an identity designer: the type suggestions lean safe, and it will not produce a logo for you.
