Question about mica color and mixing to get red hue
I am making loose mineral makeup. To color the blush and foundation, I bought red oxide and yellow oxide. Do I need to buy manganese violet and ultramarine blue to get a larger range of blush colors (which is what I want)? The red oxide is like a dark brick color, almost brown; it’s hard to imagine that if I mix the blue or violet, it will make the color brighter or more pink or brighter apple red? I understand the color wheel and have mixed paints before but it’s hard to imagine that the same will happen with these color powders. I’m asking because I haven’t bought the blue and violet yet and would like to know what I need to buy altogether before I test them out. I do not want to use FD&C colors at all.My other question has to do with the brightly colored pretty pink, red, etc micas I see on TKB trading, brambleberry, justpigments etc. It says they added red iron oxide, yellow, and/or blue and purple. How did they get a vast majority of different colors? Are they adding FD&C colors and not disclosing it?I have researched the different ingredients but I’m just trying to understand the color micas. Also if you recommend I buy anything else, ty. -

The best blush (in my opinion) is obtained with a combination of iron oxides and micas. Think of iron oxides as paint - flat and opaque. Micas are sheer and reflective. Blends of micas and oxides are more highly pigmented with the reflective quality that is more on trend at the moment. Blush is usually more sheer than opaque (so less iron oxides or titanium dioxide). The easiest way to create a beautiful blush is to use a preblended mica that is a combination of mica and oxides as your colorant in your formula. I don’t think using only oxides would make the most flattering shades of blush. May I ask why you want to avoid FD&C colorants? This is just what I’ve experienced in my blush adventures. I’m not a professional formulator by any means though!
