Colour values

Use HEX or RGB on screen. CMYK values are approximate conversions: print colour depends on the press and the paper, so ask your printer for a proof.

Colour pairings

Body text needs a contrast of at least 4.5:1 (AA). Large headings, 24 px and up, can go down to 3:1.

Pairs marked ✕ are for shapes and decoration only, never for text.

Graphic elements

Icons, a pattern, and the photography to aim for.

05.1 Graphic elements

App icon and avatar

Where space is small and square, use the symbol alone. On app icons it sits on primary at a little over half the icon width; on avatars and profile pictures, on surface.

iOS · 1024 px
Android · adaptive
Avatar · 400 px

Favicon · 32 and 16 px

05.2 Pattern

Symbol at 0° and 180° on an offset grid. For packaging, backgrounds and merchandise, never behind text.

05.3 Graphic elements

Imagery

Natural light, real places and real people. Keep rooms neutral and let brand colour appear on one object or a single overlay.

Photos here are samples from Unsplash, to show the direction.
