Corro

BRAND AND DESIGN SYSTEM · V1

Corroborated pitches.

Every prospect is a case, every finding is an exhibit, and you approve what goes out. The metaphor lives in structure and words, not decoration: no red string, no paper textures.

§ 1

Logo

Two sources: two overlapping rings, and the yellow overlap is the claim both sources back up. The rings take the ink colour of the theme; the overlap is always evidence-tag yellow.

Corro

Manrope ExtraBold, tight tracking. Always “Corro”, never all caps.

Rules

  • Keep clear space of one ring’s width around the mark.
  • Don’t recolour the overlap or fill the rings.
  • Smallest size: 16px mark, 80px lockup.
§ 2

Colour

Cool paper and graphite by day, blue-black by night. One accent, evidence-tag yellow, used only where you need to decide something.

Stamps and decisions

Each case carries a stamped stage. Yellow appears only on things waiting for you.

§ 5

Case file and exhibits

Folder-divider tabs for each case, and every audit finding as a numbered exhibit with its source and time. The exhibit below is a labelled specimen to show the layout, not a real finding.

Phone number can't be tapped on mobile

Visitors can't find a phone number on the homepage, so urgent callers go elsewhere.

What we measured: Layout specimen. A real exhibit quotes exactly what the audit observed on the prospect's site.

Technical details

Fix for the developer: Plain-English fix the Inspector attaches to each finding.
