Hi folks. I have recently purchased some Pearl Ex interference powders. I have mixed the powders with a transparent medium for airbrushing. I have noticed though that the blue interference powder leaves an off axis yellow color as opposed to being translucent like the pearl white. Any tips on correcting this?

Interference colors are made by coating tiny mica flakes with an extremely thin coats of titanium dioxide. The colors have a flip effect and the yellowish cream shade you are seeing is probably caused when the color laying over a light background. The flip or blue shade is most noticeable over a dark color. The Pearl white isn't an interference color but an iridescent color and this is why you get the opaque white as opposed to the slightly yellow/cream flip color of the blue. Unfortunately I don’t think there is anything you can do to mask this as placing white over the interference blue will prevent the color from flipping.
