Greetings! I have to airbrush gumpaste roses that I made the color Lapis. For those who do not know, this is a very very dark purple. It kind of has black undertones. I am trying to figure out what airbrush colors I can mix together to get this color. Any help or ideas would be MUCH appreciated!
It is for a wedding in two weeks from today!

Thank you!

Red and blue make purple, add black to make it darker.

The calla lilies in my gallery are a very dark purple, they look almost black. I just used the Americolor Regal purple & sprayed a few coats to make the color darker. HTH!
