On testing color contrast

When testing contrast be wary of tools that use color pickers. The picked color may differ depending on your color space settings and other factors. Always prefer direct value input.

Figma

Annotation Toolkit (Internal)

This Figma library includes annotations to use on your designs prior to developer hand off. These annotations let you document semantic structure, make visuals and interactions accessible Annotate design system components, outline DOM order, and work better together. It is active by default in all new Figma files, and can also be activated manually if needed.

A11y - Focus Order plugin

Select your elements in the desired tabbing order, add them to the plugin to get a visible layer label, and use the tab key to test the tab order from inside of Figma.

How does this help? Instead of manually placing tab order stickers on your design, let the plugin do it for you, and you can tab through your design to see if the flow makes sense.

How does this help? Checking the color contrast is one of the most important steps to take as a designer. Now you can test contrast without leaving the design tool.
