The Kendo UI for Angular ColorPalette component is [WCAG 2.1 AAA](https://www.w3.org/TR/WCAG21/) and [Section 508](http://www.section508.gov/) compliant. The component also follows the [WAI-ARIA best practices](https://www.w3.org/WAI/ARIA/apg/) for implementing the keyboard navigation for its component role, and is tested against the popular screen readers.
| Selector | Attribute | Usage |
| -------- | --------- | ----- |
| .k-colorpalette | `role=grid` | The focusable wrapper of the component should announce its role as a `grid`. |
| | `aria-label` or `aria-labelledby` | The component needs an accessible name to be assigned to it. Must also include the currently selected value in the component. |
| | `aria-activedescendent=.k-colorpalette-tile id` | Points to the focused cell in the table. The focused cell is changed via keyboard navigation. |
| | `aria-disabled=true` | Attribute is rendered only when the ColorPalette is disabled. |
| | `tabindex=0` | The element must be focusable. |
| .k-colorpalette-table | `role=none/presentation` | Negates the default role of the element, as it is wrapped within a `role="grid"` element. |
| .k-colorpalette-table>tbody>tr | `role=row` | Required as the semantic role of its parent `<table>` has been removed. |
| .k-colorpalette-tile | `role=gridcell` | Required as the semantic role of its parent `<table>` has been removed. |
| | `aria-label` or `title` | The text representation of the color value for the current cell. |
| | `aria-selected=true` | Present on the currently selected cell in the component. |
The ColorPalette is compliant with the [Section 508](http://www.section508.gov/) requirements
The component has been extensively tested automatically with static code analyzers and manually with the most popular screen readers.
