Intro
Color picker popover
Usage
Use the color picker popover if:
- Selecting any color freely is the typical use case (for example, for user-created content).
- There is no need for or benefit from a predefined color palette.
- Selecting a color is needed as a toolbar action. In this case, use a button or menu button to trigger the color picker popover.
Do not use the color picker popover if:
- You want to let users select a color directly on the page (for example, inside a form). Use the color palette instead.
- A predefined palette is beneficial. Use a color palette popover instead.
Responsiveness
The color picker popover supports cozy and compact content densities. On a phone, the color picker popover turns into a full-screen dialog.

Layout
The color picker popover consists of a popover containing a color picker and a toolbar.
The color picker consists of the following elements:
-
The color picker box for setting lightness and saturation
-
Sliders for setting the hue and transparency (“alpha channel”)
-
Form elements for:
- Displaying the current and new color settings
- Setting the color as a hexadecimal value
- Setting the color as red/green/blue (RGB) value (0 to 255 each)
- Setting the color as hue/saturation/lightness (HSL) value (hue: 0 to 360 degrees, saturation: 0% to 100%, lightness: 0% to 100%)
- Setting the transparency (“alpha channel”) value of the color (0.00 for full transparency to 1.00 for opaque)
The toolbar contains two buttons: Submit (emphasized) and Cancel.

Types
The color picker popover comes in 3 flavors:
- Simplified: The simplified color picker offers settings for hue, saturation, and lightness, but not for the alpha channel. It shows the current and new color. Text input is only possible for hex values.

- Default: The default color picker allows all settings. It displays input fields either for red / green / blue / alpha or for hue / saturation / lightness / alpha. End users can switch between both sets of input fields.
'Default' color picker popover
- Large: The large color picker allows all settings and displays all fields at the same time.

Behavior and Interaction
Colors can be selected using mouse/touch or a keyboard:
- Mouse/touch: Users select a combination of saturation and lightness in the color picker box (left click, tap, click and drag, tap and drag). Hue and alpha values are selected with sliders.
- Keyboard: The tab key is used to set the focus on the sliders and input fields. Values are entered using the corresponding input controls. The sliders react on arrow keys, page up / page down keys, as well as on home and end keys. The color picker box is not keyboard-enabled.
The Submit button applies the new color and closes color picker popover. The Cancel button closes the color picker popover without applying the new color.
Guidelines
- To trigger the color picker popover, use a button or a value help icon from an input field.
- Show the selected color in another place (for example, as a color value inside the triggering input field). The color picker popover closes as soon as a color is selected.
- Use the simplest color picker popover type that does the job.
