What color type are these rats?

I'm having a little difficulty classifying these rats.

Are the soft brown colored ones mink?

One of my breeder females:
She throws high white, low marked pups w/ cool heads. She only has that little sliver of color on her face.

This is one of her pups of the same color I believe:

Thank you

Damm there cute

They are very cute! The blueish ones look mink to me. If they have ticked hair, as in each hair has several colors then they are blue agouti.

Thank you!
There's no agouti, so I'm just going to say mink.

And I'm still not really sure about my breeder female either.
She has a purpleish hue to her color.

Would they all be variations of mink then? Or just the top few pups I posted

I forgot to ask about this little guy too.

He looks more gray in the picture than he does in person. He's in between a black and mink color.

Man, those are difficult to figure out!

They are high white though. Be careful breeding dominant high whites, they are genetically predisposed to Megacolon, an inability to pass stool.

They look mink to me.

Thanks for the warning.
Most of my rats are self, berkshire, capped or bareback.
Are the capped or barebacks considered at risk as well? Or just ones with extreme whites on their heads (like the female breeder posted above)?

I haven't seen megacolon in any of my rats yet. No enlarged bellies or anything.
Well, most are fed off once they hit around ~7 weeks (small rat size), so maybe they could have come up later on. But my adults haven't shown any signs.

I'm not 100% sure on the other colors, capped or barebacks tend to have lighter heads than the rest of their bodies, so they could still be minks.
