Intro

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 (Prior to any selection, the default color is white. However, the app developer can set a different predefined color using the setSelected method.)
  • 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: OK (emphasized) and Cancel.

Types

The color picker popover comes in 3 flavors:

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 (click 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 OK 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.
