The Hi Doctor brand
One green voice, one colour for every treatment. Everything you need to write about or show Hi Doctor correctly.
- Green v3 logo files
- Colours, gradients and washes
- Type and voice principles
The mark and wordmark
The isotype is a rounded green tile with a white cross and a light dot. The lockup pairs it with the lowercase wordmark.
Clear space
Keep a space equal to the height of the isotype's cross arm around the lockup. Never recolour the cross, stretch, outline or add other medical symbols.
Category colours
Brand green is Hi Doctor's voice. Each treatment has its own colour.
Gradients
Light, one hue plus white. Never rainbow, never dark. They re-tint on category pages because they read the page accent.
Category and product cards
Background images
Soft chroma washes sit behind heroes, feature splits and product still-lifes. Use the brand green set on company pages and the category set on treatment pages.
