Commonwealth Bank (CBA)

CBA Brand & Logo Overview

CBA’s logo is the yellow diamond, long associated with the bank’s identity.
The diamond was originally designed to reflect a “truly Australian identity” based on the Southern Cross constellation — connecting the star points with the visual of a glowing diamond.
In 2020, the logo was refreshed to a brighter, solid yellow diamond with updated typography (separating “Commonwealth” and “Bank”) to modernise the brand while maintaining global recognition.

The yellow diamond is the central visual element in all CBA branding, often paired with black or dark grey for high contrast on signage and corporate materials.

Illuminated channel letters and logo symbols installed on building façades, especially at branch or business centre entrances
These signs often feature backlit or front-lit acrylic/metal letters with the yellow diamond as a prominent graphic.
Acrylic — for logo faces and letter surfaces (durable and highly visible).
Aluminium or Composite Panels — used as backing and support structure for external signs.
CNC routing or laser cutting for acrylic and metal parts for sharp, accurate shapes.
LED strips/modules and opal diffusers installed inside channel letters to ensure even light distribution.
Completed sign elements are mounted to building façades, under canopies, or interior walls by professional installers.

Many branches and modern “future banking” environments integrate the yellow diamond and brand language into architectural elements, wayfinding signage, and digital displays.
New branch designs use a hierarchy of sign types and iconography that align with CBA’s brand messaging and customer journey.
LED Lighting — integrated inside channel letters or logo shapes for illumination, essential for visibility in low light conditions.
Powder-coated metal trim/frames — to protect edges and add premium finish.
