class: ColorPicker

[113:7] extends: Node, Control, Region

ColorPicker wraps the JavaFX ColorPicker control, a combo-box-style widget that opens a color chooser popup where users can select a color visually or enter a hex value. The selected value is a JavaFX Color object, and the control displays the chosen color as a swatch on its face. The style class color-picker is applied by default. An additional CSS property controls whether the selected color's name or hex value is shown as a text label on the button. The tables below list every CSS property available to ColorPicker, organized by the class level where each property is defined. Properties defined at a higher level are inherited by all subclasses below it.
