Interference Oil Colors
The interference colors are mica-based
colors with certain properties that interfere with the
normal prismatic qualities of mica so that certain colors
are highlighted. Put simply, they look and act like a
transparent pearl, but play with the light and throw off
color with the most mysterious effects. We make these
in Violet, Blue, Green and Red.
Imagine
the colors that shoot out of a fire opal, except each
color is isolated. For example, Interference Violet goes
on like an almost colorless glaze but the violet "fire"
picks up and reflects light, particularly on dark surfaces.
These interference colors work best in glazes as they
lose their opalescent sheen when mixed too much with other
colors.
