When we use our brand palette, we must ensure that the colours we choose for text and graphics have enough contrast to the background colour. Doing so means that the materials we create will be accessible to the largest audience. The table below lists all brand colour combinations. It shows which pairings have the required level of contrast for different uses. These uses include:
  • graphics and user interface elements
  • text and images of text.
View all examples of colour combinations suitable for: Graphical objects, text minimum (AA and AAA), and text enhanced (AAA).
Colour Accessibility Matrix. Foreground colours are the columns, background colours are the rows. Where a foreground column and background row intersect the cell shows the Web Content Accessibility Guidline (WCAG) contrast complicance level of the two colours when used together.

Explaining the matrix.
Rating Explanation
F FAIL - 285 of 441 combinations (65%).
  • Colour combination should not be used for user interface (UI) components or graphical objects where no text is used, nor for the visual representation of text.
G Contrast ratio is at least 3:1 - 156 of 441 combinations (35%).
AA Contrast ratio is at least 4.5:1 - 84 of 441 combinations (19%).
AAA Contrast ratio is at least 7:1 - 52 of 441 combinations (12%).
NOTE Exclusions for visual representation of text are:
  • Incidental: Text or images of text that are part of an inactive user interface component, that are pure decoration, that are not visible to anyone, or that are part of a picture that contains significant other visual content, have no contrast requirement.
  • Logotypes: Text that is part of a logo or brand name has no contrast requirement.
