My friend needs help ladies

My friend is getting married upstate. She wants dark purple roses in her bo-k. Her florist keeps showing her roses that are more red tham purple.

I know people have used purple roses, can anyone tell me the name of the rose, etc.? Thanks in advance!

ETA: I see that someone posted about purple flowers just yesterday. Sorry to be a pest, just need the name of the rose. Her florist seems to be without a clue!
