How can I get the color a UI Button has in the moment?
use the following method: your_button_UI.color
Declare a public variable in your script as following:
//for instance at here we take is an image public Image your_image_name;
//make a public color to show you in the editor what color is your button
public Color your_image_color;
The following line shows the color of the UI image in the editor through the above Color variable:
your_button_color = your_image_name.color;
