Red+yellow=orange
Blue+red=purple
Black+white=grey
A google image search has some basic colour mixing theory/examples of different ways to approach mixing.

Sitting down with a piece of paper and working through some of the colour wheels in real life is a sensible start to get you used to it.
Save up for a Mephiston Red!
Then you'll have 3 primaries red , yellow, blue.
Black and white
And a metallic.
With careful mixing you can make many colours, washes, highlights. As you find yourself mixing a certain colour often then it's probably time to invest in it.
Make a wet palette as it'll save paint and make your life far easier if you're doing a lot of mixing.
