I was cleaing cages yesterday and got a few good photos of my leucistic kaouthia.

I try not to get carried away with different morphs but I can't resist these!

Is that another name for albino. Anyway nice cobra mate!!!!!!!!!!!

Leucistic and albino are different. Correct me if i'm wrong but i believe albino is the reduction of melanin, leucistic is the reduction in all pigment.
 
Not the same. Albino, aka amelanistic, is without melanin, or black pigment. That's why you see yellow / orange colors on albinos, that pigment remains while the melanin is absent. Here's a picture of an albino monocle I have.

Okay, it is a bad picture, but you can see red / orange color. In a leucistic the pigment is gone, so it is white. The skin isn't clear, at least not as it ages, so you don't see the pinkness of the blood through it.
Granted, there is a bit of color, looks like an ashy smudge, on top of its head. I know that some leucistics, Texas rat snakes for an example, had these sort of marks in early generations but they didn't appear in later ones.
 
Not questioning you just didn't know myself thats why i asked.

Don't worry, I did double check before I answered. One thing that makes it confusing is that not all animals have the same pigment. Reptiles have melanin pigment, for black, and xanthic pigment, for yellow. Here's a picture of a hatchling albino, aka amelanistic, with a normal.

You can see how the yellow on the albino corresponds to the brownish areas on the normal, and the albino's white areas are where the black is on the normal.

Here is a picture of a ball python without the xanthic, or yellow / brown, pigment. This is called axanthic, ie "without xanthic pigment, just as the amelanistic is without melanin, black pigment. The coloring on these snakes is pretty simple, with basically those two pigments. When you compare the normal with the albino and axanthic you can tell the color on it is either black or brown, and the brown is a mix of black and yellow (on ball pythons). There are ball pythons bred that are both axanthic and amelanistic, usually called snow. It is solid white with red eyes. If I had one of those I would throw up a picture but hey, I don't have everything.
Other animals have more pigments and that's when it gets really complicated.
A sort of interesting comparison is with people. On a simple level that makes sense to me, humans only have melanin in their skin. If you look up pictures of amelanistic / albino people they are creepy scary ghost looking things!
I hope that makes sense. I have a very basic understanding of the genetics and don't always explain it clearly.
Glad you like the cobra pictures!
