Is There a Blue on My Fingerprints?

It depended on the light rigt, cause there wer so many dfferent sources of light coming into the building. There was times where i thought it had like a blue hue on it. I keep night black on it. Everyone yells at me, just midnight. But eaven, this silver, like even my thi silver one,. So ihaven't cleaned it in a long time, and there's finger prints all over the place - but it doesn't show us as much as it wold on.
