you can get color of pixel where you touch in background. after that replace that color with another color. To detect color i used ColorPickerImageView class. you can download that class from this link https://www.assembla.com/code/GeoBattle/subversion/nodes/xcode/Classes/ColorPickerImageView.m?rev=189

this may helps you
