Colour
POST's brand colours are POST Blue and white. Black is also used.
POST Blue is a highly saturated RGB colour, so print in Pantone Coated wherever possible. For the same reason, matching it in print and materials can take a bit of work.
Brand
The anchor. Brand blue is the primary; white / black are the base surface + text. The only color that lives in Foundations — Web and Marketing import these and build their own ramps.
Sub-brand
Each sub-brand color = a physical destination / vertical inside POST.
Utility surfaces
The warm surface set imported by every branch.
On screen: two axes
A page picks a sub-brand. A section inside it picks a theme. The two are independent, so the same component resolves differently depending on where it sits - without a second set of components. Switch both below; every preview on this page follows.
POST Brown is reserved for web use, such as navigation menus and modals.
