Can someone help me I'm trying to dye some white roses,
I would like to get them to be a dark blue .
Are you trying to dye real roses or artifical ones? If real, put blue color in the water and they will turn blue, or different shade of blue. If artifical, try a air spray paint--as I am not familiar with the procedure, or the type of paint you can go to a large craft store like Michaels, Hobby Lobby etc, or contact a magazine like Crafts/n things.
