Looking for a way to use an iPhone camera to determine whether a specific area in a photo is red or blue?

The goal is to create an iPhone app that will take a picture of a QR code. One corner of the code will be either red or blue, so we need the app to take the picture and then display a message saying that it is "red" or "blue."

I'm looking for either a code that does something similar to this or really any help, no matter how small would be very helpful.

Thank you.
