<theme_item name="sample_bg" data_type="icon" type="Texture2D">
Background panel for the color preview box (visible when the color is translucent).
</theme_item>
<theme_item name="sample_revert" data_type="icon" type="Texture2D">
The icon for the revert button (visible on the middle of the "old" color when it differs from the currently selected color). This icon is modulated with a dark color if the "old" color is bright enough, so the icon should be bright to ensure visibility in both scenarios.
