Could you mix them with oils such as vegetable oil or some cocoa butter or beeswax and make oil paints out of them( granted you have all these ingredients)?If you have iron oxide powdered pigments?
There's a whole specific process to making oil paints from pigments and a binder (linseed oil: not wax or just any oil), which entails ';grinding'; the ingredients together: it's not just a matter of mixing them. I had to do it for a course in art school. You use a flat-bottomed glass pestle and a glass grinding plate like these:

You have to grind and grind and grind, pressing and swirling the pestle around in a circular motion and scooping up the mixture that squishes out to the sides with a spatula or palette knife to bring it back under the pestle, regrinding continuously until the pigment particles are ground as finely as possible and the paint is perfectly amalgamated and of the right consistency. It's also a matter of dosing the oil properly, a little at a time. It takes some practice to master the process.
When the paint is ready, you then have to put it into a paint tube and seal the bottom properly.If you have iron oxide powdered pigments?
Linseed oil is the primary vehicle used in oil paints. You need to be extremely carefull when using powdered pigments!!!!! Most are oxidized metals that are very dangerous if inhaled, brain damage, cancer, and nervous system damage are known effects of exposure to heavy metals.
you should find out the proper way to make paint before you do anything... and ALWAYS!!!! use a respirator with the correct chemical or organic filters. Powders are dangerous stuff ok.
