Remember when you are comparing UIColors you have to write description at the end of the color for both side, if you don't write this, every time it will enter into else block. For Example, see the below code

if(ocularPlus1Btn.backgroundColor?.description == UIColor.init(red: 23.0 / 255.0, green: 82 / 255.0, blue: 84 / 255.0, alpha: 1).description) {
   return "positive"
} else {
   return "negative"
}
