I have seen 7 color rose flower: Rosy, Red, Pink, Black, White, Black, Blue. American Rose Club of California may the world largest Rose Club and they celebrate many events say Miss Rose Queen, World Rose Queen and give prizes to winner. Miss Emilee Alison a 3 years old baby was Miss Rose Queen last year (see her photo. Lot of information about rose, its event and compteition can be known from www.americanrose.com web site. It is a giant place for rose lovers and rose growers worldwide. My wife's elder sister and her husband was a member of this club as they are growing rose in their building's roof and won 1st prize in our country's competition.

I dont how many colours exactly. I used to have my own rose garden and I planted all colours and kinds that were available in my country. Here are the colours that available here : red, blackish red (velvet red), pink, hot pink, white, yellow, orange and purple. I've read in a magazine that blue rose is available, but I havent seen it. Cheers!
