Out of the box, the Kendo React ColorPicker provides extensive accessibility support and enables users with disabilities to acquire complete control over its features. The ColorPicker is compliant with the [Web Content Accessibility Guidelines (WCAG) 2.2 AA](https://www.w3.org/TR/WCAG22/) standards and [Section 508](https://www.section508.gov/) requirements, follows the [Web Accessibility Initiative - Accessible Rich Internet Applications (WAI-ARIA)](https://www.w3.org/WAI/ARIA/apg/) best practices for implementing the [keyboard navigation](#keyboard-navigation) for its `component` role, provides options for managing its focus and is tested against the most popular screen readers. ## WAI-ARIA This section lists the selectors, attributes, and behavior patterns supported by the component and its composite elements, if any. The ColorPicker popup contains in itself ColorGradient, ColorPalette, a UI to switch between them, and a button to reset its value. All the containing elements must implement their own specification apart from the ColorGradient element where some changes are required. ### ColorPicker Wrapping Element | Selector | Attribute | Usage | | -------- | --------- | ----- | | `.k-colorpicker` | `role=combobox` | The focusable element of the component should have role `combobox` (an input with popup). | | | `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-haspopup=dialog` | Indicates the component has a Dialog Popup. | | | `aria-expanded` | Announces the state of the visibility of the popup. | | | `aria-controls=.k-colorpicker-popup id` | Points to the popup element. Signifies that the `combobox` element controls the `dialog`. | | | `tabindex=0` | The element must be focusable. | | `.k-invalid,.ng-invalid` | `aria-invalid=true` | Attribute is rendered only when the picker is in form and announces the valid state of the component. | | `.k-colorpicker.k-disabled` | `aria-disabled=true` | Attribute is rendered only when the picker is disabled. | | `.k-colorpicker.k-disabled .k-button` | `disabled` or `aria-disabled=true` | Attribute is rendered only when the picker is disabled. | ### ColorGradient in the Popup | Selector | Attribute | Usage | | -------- | --------- | ----- | | `.k-colorgradient` | `role=none/undefined` | The ColorGradient element must have its role removed. | | | `aria-label=undefined` | The ColorGradient element must have its `aria-label` attribute removed. | | | `tabindex=-1/undefined` | The ColorGradient must be removed from the page tab sequence. | ## Section 508 The ColorPicker is fully compliant with the [Section 508 requirements](http://www.section508.gov/). ## Testing The ColorPicker has been extensively tested automatically with [axe-core](https://github.com/dequelabs/axe-core) and manually with the most popular screen readers. > To report any accessibility issues, contact the team through the [Telerik Support System](https://www.telerik.com/account/support-center). ### Screen Readers The ColorPicker has been tested with the following screen readers and browsers combinations: | Environment | Tool | | ----------- | ---- | | Firefox | NVDA | | Chrome | JAWS | | Microsoft Edge | JAWS |
