Color Picker

HSVA color control with manual and audio-reactive modes

A Color Picker exposes a full HSVA color selector to the operator. All channels (Hue, Saturation, Value, Alpha) are delivered together through a single bound event — the developer chooses which channels to consume and how to combine them.

Configuration

Color pickers are declared inside UICategories on the xrlive_UIpanel component. Set Type to Xrlive Color Picker and fill in the fields below.

Field	Type	Description
Name	String	Unique ID of the control. Must match exactly (case and spaces) when referenced in Blueprint.
Tooltip	String	Optional helper text shown to the operator on hover.
Default Color	Color	The initial color value when the visual loads. Set using the inline color picker.
Audio Reactive	Bool	Controls whether the audio-reactive toggle button on the color picker is enabled or disabled in the operator panel. The button is always visible regardless of this setting. When enabled, the operator can activate or deactivate audio-reactive mode at runtime. When disabled, the button is visible but non-interactive.

Blueprint API

Standard mode

Use this wiring when the operator controls the color manually.

Call Find Control by Name on the xrlive_UIpanel reference, passing the color picker’s Name. Feed the Return Value into Bind Event to On Color Picked. Create a Custom Event and connect it to the Event pin.

Standard color picker wiring — Find Control by Name feeds Bind Event to On Color Picked

Pin	Type	Description
Control Name	String	The name of the color picker that fired the event. Useful when one event handles multiple color pickers.
Color	Linear Color	The full HSVA color value selected by the operator. All channels are available from this single pin — use the individual channel outputs as needed.

Audio Reactive mode

When Audio Reactive is enabled, wire Bind Event to On Beat Color in addition to the standard bind. This event fires in sync with the audio beat signal.

Audio-reactive color picker wiring — Bind Event to On Beat Color replaces the standard bind node

Pin	Type	Description
Beat Color	Linear Color	The HSVA color value driven by the audio beat signal at runtime.

When Audio Reactive is enabled, both bindings should be wired: Bind Event to On Color Picked handles manual operator input and Bind Event to On Beat Color handles the audio beat signal. The two events fire from independent sources and do not interfere with each other.
