The mark and wordmark
The isotype is a layered two-tone cross: a solid vertical bar over a lighter horizontal bar. The primary logo pairs it with the rounded lowercase wordmark.
Category marks
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.
Isotype: keep one cross arm of clear space on every side; minimum size 20 px.
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
