I hope I'm not asking you all to divulge a trade secret, but I am curious if any if you are able to achieve a nice purple color with dyes for bath bombs?
I keep trying to create a blend, and I can get a purple when mixing a bit of the dyes with water. But, I use a bit of that water on some baking soda to "bloom" it, and I usually get a greenish blue or gray pile of baking soda.
Is there a trick anyone would be willing to share?

Interesting! Have you tried to use a bit more?
I haven’t tried to mix dyes for bath bombs. When I use one color, I mix it dry with the dry ingredients, and when I spritz they mix with witch hazel to mold it, that’s enough for it to bloom.

I tried to get a nice purple using dyes (WSP) and ended up with black water. Haven't tried again. I generally had better luck with micas.

Just in case this comes up in a search or something...
Red 40 and Blue 1 do not make purple. Something about the orange undertones in Red 40 doesn't mix well with the Blue 1. Apparently, Red 28 & Blue 1 is the way to go for purple.
