For the guys and gals that don’t know they are designed to be mixed with either clear or coloured paints and result in a nice special effect finish.
Bit on the pricy side though. [;)]
The Starter sed has green, blue, purple, pink, orange, and yellow pigment in it.
My only experience with pearl powders was Ultra Pearl line by LMG Enterprises many moons ago. I used the Satin White and the White Euro Pearls. The results were fantastic! A little powder goes a long way but I forgot what the mixing ratio was. I remember mixing in too much powder once and got a “white aluminum” effect so you’ll have to experiment a bit, I guess. Hope this helps.
