Travel to Venus
When you rub the powder between your fingers, you will note that it is exceptionally soft and smooth (thanks to the silica). You will also see the whiteness disappear as it turns a bright, luminescent purplish pink.
If you rub the powder across a piece of white paper with black background and tilt the paper, you will see a subtle shift from the pink hue shiver over to a silver then a pastel green-blue. This is the color-shift in action.
Here are the guidelines for "best use":
◦*Use the color alone or in with small amounts of dark colors such as blue, black or green
◦*Use in transparent, translucent or semi-opaque formulas (for example: lip gloss, not lip stick)
◦*Mix it gently (avoid grinding it in a mortar and pestle or blender)
◦*Package in transparent packaging to show off the color shifting
