The color of the holographic powders stand out best when applied over a similar colored based. The holographic rainbow effect is present when burnished over any color base. A different colored base will change the intensity of the powders primary color.
This is NOT glitter, it is a holographic powdered pigment meant for use in crafts, makeup, and nail art. It is not soap safe.
Photos explained: the first photo shows the color over a white base on the left and a black base on the right. The photo with the cars shows the color mixed in with clear medium on the left and in black on the right.
