Spike is orange, with a white belly, white boots, and a white smudge across his nose. He also has a patch of darker fur on his side; when he was a kitten, I thought it was paint and tried to wash it off.
Oz falls somewhere between a grey and a brown tabby, with black stripes. He's hard to describe (the Humane Society had him listed as a brown tabby, our vet says he's grey, and I think he's black with brown and grey undertones), but has a beautiful coat and a very distinctive tabby mask.
I wish I had a digital camera so I could post pictures of my babies! They're so purdy!
