How to assign a background color to a UIImageView that is below it?

Question

iOS

Good day.
I have two pictures of different sizes superimposed on each other. The bottom picture consists of two colors: white and red. Tell me how to make the background-of the top image assigned the color of the bottom one?
Thank you.

Use the UIImage class method:

+ (UIColor *)colorWithPatternImage:(UIImage *)image
