Blazor FlatColorPicker Accessibility

The Telerik UI for Blazor FlatColorPicker component is WCAG 2.1 AA and Section 508 compliant. The component also follows the WAI-ARIA best practices for implementing the keyboard navigation for its component role, and is tested against the popular screen readers.

Wai-Aria

The FlatColorPicker contains in itself ColorGradient, ColorPalette, a UI to switch between them, Cancel, Apply, 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.

FlatColorPicker wrapper

Selector Attribute Usage
.k-flatcolorpicker role=textbox The focusable wrapper of the component should be considered a textbox. That signifies it has a value that could be submitted.
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-invalid=true Attribute is rendered only when the selected value in the component is not valid against the current validation rules.
tabindex=0 The element must be focusable.
.k-flatcolorpicker.k-disabled aria-disabled=true Attribute is rendered only when the ColorPalette is disabled.

ColorGradient

Selector Attribute Usage
.k-colorgradient role=none/ The ColorGradient element must have its role removed.
aria-label The ColorGradient element must have its aria-label attribute removed.
tabindex=-1/ The ColorGradient must be removed from the page tab sequence.
