Design system
Colours, type and components for the Platy web app, derived from the logo, the only brand asset so far. Every text colour reaches WCAG 2.1 AA contrast (4.5:1), and every focus ring and field border 3:1, in the light and the dark theme.
Logo
A single-colour mark. Its white details are cut out, so the same file works on light and dark backgrounds.
- Brand teal #09C6C2, sampled from the logo, reaches only 2.1:1 on white. It is for the logo and decoration, never for text or controls: interactive teal is the darker primary.
- The files are derived from the 640 px logo image until a vector original is available.
Colour
Every pairing the components use, with its contrast ratio in both themes. Values come from the design tokens in globals.css.
