Working with accessible palette

Accessibility utilities can calculate contrast, inspect markup and help draft descriptions. They answer specific questions, but a usable experience also depends on navigation, context and the way content is presented to people using different technologies.

Common questions

Does every image need a long description?

No. The useful description depends on the image’s purpose and nearby text. A decorative image and a chart conveying important information need different treatment.

Can an automated pass certify the whole experience?

No. Automated checks cover only part of the problem. Use them to find issues, then review interactions and content with the intended users in mind.
