This is going to sound dumb, but how do I get a nice pale violet/lavender? I use Americolor and Wilton. I have used Violet and Royal purple. The shade I make always seems to have a gray undertone. Can anyone help?

try this link for color mixing:

Thanks, wouldn't of thought it would require such a pink base.
