Black Himi vs Chocolate Himi & Blue Tort vs Opal

[MamaMandy]

How can you tell the difference between black and chocolate himis? I bought what I was told was a black himi Netherland Dwarf but her points sure look chocolate to me.

I also have a broken buck that I'm just not sure if he's an Opal or Blue Tort. What do I look for to tell the difference?

Thanks in advance for any input!

Opal will have rings of different colors in the fur, http://www.angelfire.com/tx5/doublehrab ... color.html

Thanks! I blow into his fur and I see different colors but they don't look like distinct rings. Maybe he is a blue tort. The nape of his neck is fawn so it had me wondering if he's opal, but I guess a tort would possibly have fawn there too.

Concentric rings, I believe is the right description. My main pattern in rex is agouti, so agouti ring patterns are important to me. Though I had an opal without an intermediate ring color for a while.
