+	<brief_description>
+		A resource class for managing a palette of colors, which can be loaded and saved using [ColorPicker].
+	</brief_description>
+	<description>
+		The [ColorPalette] resource is designed to store and manage a collection of colors. This resource is useful in scenarios where a predefined set of colors is required, such as for creating themes, designing user interfaces, or managing game assets. The built-in [ColorPicker] control can also make use of [ColorPalette] without additional code.
