Google for color wheel so that you can better judge the color percentage. And do it in sunlight for accurate shade tone.

Shades making is quite technical work but not difficult. You have to follow the tone of shade.

In makeup 99.9% shades made with yellow oxide and red oxide. First of all add yellow oxide and check your shade if it needs more brownish or skin tone add small amount of red oxide. Remember to note down each addition of color.

@Belassi thanks for your reply. In this case should I go for some emulsion to mix with powder phase?

I mix all metal oxides together with  kaolin and red oxide and yellow oxide in a mortar. (I call this phase powder phase)

Then I need to make a dough. In my beginning I use simple water but after 2 months water evaporated and aqua makeup converted into shrinked cake that was moving in packaging jar. 

Could you please direct me to right path. Just need an emulsion that Hold my powder phase in stable shape. 

I had tried polawax, water and paraffin emulsion but batch lost waterproofing and washed quickly. 

And @Bobzchemist thanks to you too for keeping eye..
