Colour Accessibility

We aim to make Lens an accessible design system for all. To this end we work towards WCAG2.0 AA standard accessibility.

A small but vital part of these efforts are to make sure we use colour combinations that have enough contrast so that they are clear and readable.

The examples shown below that are marked as accessible are combinations that our currently used on our website. Whereas the examples marked as not accessible are not used on our website and are shown purely as an example of a bad combination.
