GREEN BLOTCHED SNOW CORN.  I know, you're probably thinking "Hey, where'd the green-blotched snow corn in the thumbnail go?" That's what I thought too when the big picture directly below came back from the developer.  I could swear I saw at least a slight tinge of greenish color when Bill took this picture outside.  After contemplating it for a few minutes, now I think I'm starting to understand what the confusion is all about!

FACT:  Corn snakes don't have green pigment in their bodies.  They don't have blue either, yet sometimes we see a trace of it depending on 1.) the angle at which the light hits them, and even more importantly, 2.) the quality of the light hitting them.  The difference between light bulbs, fluorescent lighting, and natural daylight truly makes a huge difference in what we see.  Corns do have yellow pigment, and when we factor in those illusive iridophores (reflective cells) in their skins that account for whites, prismatic luster, bluish tinges, etc., I think the 'green' we sometimes see is also a byproduct of that effect.  And, it's tough to capture on film.  So, I can provide 'Green Blotched Snow Corns' as good as anyone else's, but please be forewarned that they will not always appear green every time you look at them.

O.K., there's one other way to bring out the green.  Page down, below this pic...
 BELOW:  Amazing what just a few seconds tweaking the hue and saturation in Photoshop can do to bring out those hard-to-show greens.   ADDED NOTE - I could have easily made the blotches much greener, but a good faker would stop here so it looked credible, not absurd.  Compare and beware!
