Take 7 teaspoons of coconut oil and 3 teaspoons of beeswax pellets and melt them in a plastic cup in the microwave. Start at 30 seconds and stir until melted.
Add 3 spatulas of red matte mica powder and 2 brown matte mica powder. Stir.
Add three drops of geranium essential oil if desired.
Stir well and carefully pour into the lip balm containers.
Notes
You can increase or decrease the amount of beeswax or oil to make the balm harder or more gloss-like. The more wax, the harder it will be. Test it by dipping a spoon in the melted mixture and set it in the freezer for a minute. When you take it out you can try it, and see if you want to adjust the firmness accordingly.
If your mixture comes out lumpy when you pour it into the tubes, you can use a dryer sheet to help smooth out the top of the balm.
You can use any essential oils you like. Lavender is always a safe bet. Flavored extracts like peppermint work well too.
I used the little spatula that came with the mica powders. If you buy something different, you will just have to experiment with a plastic spoon to get the perfect shade.
