Ok, this is personal opinion you understand. But I think going with all the same color of rose makes a bigger statement than going with different colored roses. When I get home tonight, I'll have to find a picture of my front yard surrounded by a hedge of yellow roses, with an arbor and two yellow climbing roses at front and center.
You could do two colors that compliment each other, but I would do them in groupings. Like 5 purple rose bushes and then 5 yellow rose bushes. Still would make a wow statement.
Just things to think about.
