Fingerprint, original file

I knew I wanted to get a copy of my fingerprint to use for the bar code collage but found it's not readily available through the "official" channels. As I was applying for a loan for a new truck, I had to put my fingerprint on the application form. I asked the guy at the bank if I could make a fingerprint to take with me.
When I scanned the original fingerprint into the computer and started to blow it up to be used for the large collage, I noticed there was more than just shape and texture. There was color specs that I thought were interesting in themselves. So, . . . I've kept exploring the images just for fun. the "blow-up" is a whole other story.
