White was chosen as the background colour of the website due to colour contrast and readability reasons.
Since one of the primary colours used throughout the website is the EC Yellow (#ffd617) depicted on the Primary colours section below, using a shade of grey or a tint of any other colour would greatly reduce the visual contrast between this colour and the background colour.
The primary colours: blue, yellow and grey.
Only use colours to highlight important content or actions. Use sparingly.

WCAG (Web Content Accessibility Guidelines) ensure that content is accessible by everyone, regardless of disability or user device. To meet WCAG standards, text and interactive elements should have a colour contrast ratio of at least WCAG 2 AA Compliant (18pt+). This ensures that viewers who cannot see the full colour spectrum are able to read the text. The options below offer colour palette combinations that fall within the range of Section 508 compliant foreground/background colour contrast ratios. To ensure that text remains accessible, use only these permitted colour combinations.
There are a number of online colour contrast checkers that should be used to validate designs before they are published.
