Newbie questions here....I looked at the Desert Ghost and I looked at another pic of an Axanthic as well as other Desert Ghosts....

1) some other Desert Ghost pics I found online look more "brownish" then this snake which looks more black/silver to me

2) this more black/silver Desert Ghost looks like some Axanthic's pics I've seen

Please educate me, I feel a bit dumb here not being able to understand what I'm looking at...what am I missing?
