Although the coffee and the stripe you have do resemble this animal as far as the thin striping goes, I think they are all different. I think Wyatt has the one animal that resembles mines the most. I am hoping I am right since the Coffee ball look like it may not prove out. I'm also hoping the Snake Keeper just had a fluke in their breeding trials and will succeed later on, it's a cool morph.
Actually the two animals you posted have a Black Pastel look to them. The Black Pastels are not posted frequently, but they have an unmistakable look and the Pewters they produce are insane. Ian Gniazdowski (this is the proper spelling for those who like to mispell his name, lol) is the only person to produce Black Pewters as far as i know. They were at the 03 MARS show for those who may have attended. Okay I stray... back to the topic at hand.
Here is a baby pic of my Hyper-Striper. You can see why I described him as Hypermelanistic. I use the term hypermelanistic to describe any animal with an unusually high content of dark pigment when compared to the average Ball.

Here's a picture of a CH animal that I consider to also be Hypermelanistic without the striping.

Further more, I think the really nice Hi-Contrats albinos are a result of increased melanin. More pigment equals a deeper, darker, orange albino.
