This is sort of complex to describe, but anyway.
On the blender console, look for a little icon shaped like a box - when you click it, it changes tohe bootm menu. On the roght-most side of the menu, there's a 'show double sided' buttom. click this - black areas have correct normals. silver are flipped. (note - if you're on double sided mode, all remians silver).
To flip the normals, slect the vertices, and use a button in that same menu - 'flip normals' , handily enough.
Neat tip - if you make a box, it starts with all the normals flipped. So I normally start from a cube, flip the normals (all faces), and extrude from it - most, if not all, normals should be fine
