This behavior will Trigger an event immediately when executed. As soon as the behavior is executed it will return the objects color/tint.
The object you want to get the color from. By default the current object is selected, but you can tap the graphic and choose any other object in your scene.
This is the color of your object returned as a HEX value. Eg. White is #FFFFFFFF
This outputs the Object ID.
If you changed the color of your object, and what to see what color it is you can use the Get Color behavior to retrieve the new color.
