Default color format to use in value binding is hex and other possible values can be rgb and hsb using the format property.

Reactive Forms #
ColorPicker can also be used with reactive forms. In this case, the formControlName property is used to bind the component to a form control.
Accessibility #
Screen Reader
Specification does not cover a color picker yet and using a semantic native color picker is not consistent across browsers so currently component is not compatible with screen readers. In the upcoming versions, text fields will be introduced below the slider section to be able to pick a color using accessible text boxes in hsl, rgba and hex formats.
