ColorPicker Customization
The ColorPicker allows you to customize the following building blocks:
Views Toggle Buttons
When both the Gradient and Palette view are present, the user can toggle between them through the view buttons rendered in the header of the ColorPicker popup. The order of the buttons will be determined by the order specified in the views
array.
If only a single view is specified, the view toggle buttons will not be rendered.
The following example demonstrates the toggle buttons in action.
Clear Button
The ColorPicker provides an option to display a clear button, through the clearButton
property. It allows the user to clear the current ColorPicker value.
The following example demonstrates the clear button.
Action Buttons Layout
When the preview
option of the ColorPicker is enabled, it will display the Apply
and Cancel
action buttons in its footer. The layout of the buttons can be customized through the actionsLayout
property.
The following example demonstrates how to customize the layout of the action buttons.
Palette View
To change the appearance in the popup when the ColorPicker displays its palette
view, utilize its paletteSettings
option.
The paletteSettings
interface exposes the following options:
-

view, utilize its gradientSettings
option.
The gradientSettings
interface exposes the following options:
contrastTool
—Provides an option for displaying a contrast tool. It ensures the user that the selected color meets certain contrast requirements e.g. AA or AAA.opacity

The following example demonstrates the gradient settings in action.
Displaying Icons
You can enhance the visual appearance of the ColorPicker by displaying an icon to the left side of its button. In this case the selected color will be displayed right below the icon which allows you to bring visual context about the purpose of the selected color.
To display an icon, use either of the following options:
icon
—Allows you to use a built-in Kendo UI icon by providing its name, for example,edit-tool
. Check the list of web icons provided by the Kendo UI for Angular suite.iconClass
—Allows you to use custom icons by providing the full icon CSS classes which will be rendered.
The following example demonstrates how to visualize Kendo UI and custom icons in the ColorPicker.
