Get background color while using "click image" activity

I want to click on image and I am using “click image” activity.
Now, the color of image is dynamic, so how to identify the click on image based on dynamic color.
Based on different (around 15 colors )colors I have to do tasks.

try clipping region property by pressing F3 and select the region in the same “click image” activity

Did you find the function that makes me know the background color of an image ?
