Brand guidelines: mark what matters.
HealthDocus looks like a well-kept patient record: precise, calm, and annotated where it counts. These are the pieces and the rules for using them.
The logo
Two figures, patient and provider, forming a heart around a pulse line. Care between people, measured and alive. Use the full lockup wherever there is room; the heart mark stands alone for icons and small spaces.





Clear space equals the height of one figure’s head on every side. Minimum size: 20px for the mark, 120px wide for the full lockup. On dark backgrounds use the light version, with a white “health”.
Colour
Restrained neutrals, one committed ink, one annotation colour.
Brand
Rx ink carries the brand: links, primary actions, and the one drenched moment per page.

The highlighter
Patients compare 21 doctors. Be the one they choose.
Use .marker on at most one phrase per section: the words a physician would underline on a chart.
Voice
- Clinical, not corporate
- Write like a trusted colleague at the nurses' station. Short sentences. No hype words.
- Evidenced
- Every statistic names its source. Illustrations say they're illustrations. Results are real or absent.
- Doctor's-eye
- Lead with the physician's reality: time, reputation, patients. Marketing jargon comes second, if at all.
Don't
- Recolour, redraw, or separate the figures in the heart mark.
- Use Marker as a text colour or a large background.
- Stretch, skew, rotate, or outline the logo.
- Retype the wordmark or change its navy and blue split.
- Publish a number without a source, or a mock without an 'Illustrative' label.
- Use stock photos of models posing as specific, named clinicians.
