A sub-brand page showing the CIBSE Certification lockup in green, both as full-colour on white and reversed white-on-green.
Summary
The CIBSE Certification sub-brand page: a blue copy panel sets out the rules while the certification lockup is shown in green, once full-colour on white and once reversed in white on a green block.
Visual description
A tall cobalt panel on the left explains that CIBSE Certification uses the secondary green (Pantone 2456 C) to differentiate, lists full-colour, white (REV), boxed and black (MONO) versions, and notes the same general rules apply. The right side shows two large stacked lockups: the hawk mark above "CIBSE / Certification Ltd" rendered in green on white, and the same lockup reversed in white inside a solid green rectangle. The hawk and wordmark structure matches the master logo, only the color and the "Certification Ltd" descriptor change.
Key takeaway
Differentiating a sub-brand purely through a single secondary palette color while keeping the exact master logo construction, which signals a clear parent-child relationship without a redesign.
Reuse notes
A clean model for documenting a certification arm, product line or subsidiary that should read as part of the family. Reusing the master mark and shifting only color keeps governance simple.
