Our core colours

Our 3 core colours are: deep violet, powder blue and midnight black. 

Deep violet is used in our logo and is the common thread across our communications.

Our colours do not have to be applied in large blocks. This can sometimes become overpowering. Using our colour palette as accents on a white or neutral base is encouraged.

Off-white backgrounds

In digital applications, it is good practice to use an off-white background colour. This will help minimise eye strain and create a better reading experience for people with dyslexia.

Depending on the content, a 3%, 5% or 10% tint of our core colours can be used.


Our wider colour palette

Our wider palette is made up of 12 colours, named below. These can act as a lead colour with the violet appearing as an accent colour. This helps us to create a flexible yet consistent approach.

Accessibility

When typesetting, colour contrast must be taken into consideration. This is especially important for people with a visual impairment. 

Text should be written in violet or midnight black. 

Powder blue can be used as a text colour on a violet or midnight black background. 

Reversed white text can only be used as set out in the guidance below.

The guidance below shows what combinations meet either AA or AAA levels of accessibility according to Web Content Accessibility Guidelines (WCAG).

Eye strain

Using pure black and white colour combinations in digital design can cause eye strain due to their high contrast. Using softer shades such as midnight black and a low percentage tint of midnight black will help to reduce eye strain. This advice is specific to digital screens and does not apply to print.
