Rose with Multiple Colors

I was window shopping last Saturday when I saw a multi-colored rose sold in a flower shop. I didn't bother to ask because I'm not buying it. Do you think that it is possible to plant a rose with flowers having multiple colors?

The colors in the flower were light blue, pink, and white. I think they have sprayed on the flower but it looks so natural.

Helper,I think your on to something when you said sprayed.I used to work in a greenhouse and that was one of the tricks of the trade. russ

Most cases they are painted on, but I know you can get more than one colored rose on the same bush by grafting different pieces on your bush.
