I thought I was being clever just grabbing the RGB value with an eyedropper-like tool, but turns out that's completely useless because it will produce different results depending on how I have my monitor calibrated. I guess it'd technically be possible to brute-force the answer considering it's only 9 digits and not all of those are likely solutions, but I'm curious about the process of analyzing an image. Any nudges in a general direction about where I could learn more about this? I use C, specifically.

BMP and TGA are relatively simple ones, so I think you can start with one of them. Well, I solved this challenge with Photoshop...
