How to wear wet makeup with dry makeup (and vice versa!)

There seems to be some confusion about what goes first and what matches (texture-wise) when it comes to makeup application. Now, there are several makeup textures - powder, cream, liquid, and gel. The general rule is to match wet textures with each other (cream, liquid, gel) and powder over powder.

Nonetheless, we always need to mix products so it's important to know what should go with what. You don't want streaky and uneven application, right?

For example, powder blush MUST go on over some kind of powder base (foundation or setting powder). If you apply it on top of liquid or cream foundation, you'll find that you'll get nasty streaks and too much color! The wetness will "grab" the pigment on the blush and make it brighter where it's wetter.
