Thanks for your inputs! I'm going to have to try to take better pictures that show the colour better. I'll see if I can throw everyone in a box with some of the common ones (albino, black, agouti) and take them out into the sunlight! In real life, those "blues" look exactly the same colour as snakesRkewl's pictures. The darkest one started off looking just like the blue agotui, with that orangeish blue cast, the middle one looks like the one just called blue. Looking at lots of pics online now that I have the "triple dilute" phrase to look for, I think that's exactly what that third one is.

On the Himi/Siamese male, he's only 4 weeks old. He's mostly white, the same colour as his brother, and then about halfway down his back, he starts darkening. You can easily see the colour stop halfway down his tail. I think his nose MIGHT have a little colour on it, but it's really hard to tell. His ears are still light, then same as his albino brothers. He does seem to be darkening more the older he gets. He was probably 2 weeks old before I could even tell there was a difference between him and the albinos, which is good because that was the first cull to the freezer! I saw he was different and held him back, so now he'll grow up to be a daddy.
