I suck at explaining things ^^" but I'll try to explain it if you want me to!

Alright,so I use the default colors or whatever.I use the darker black to do the line art of my drawing.then I use the lighter black to fill the page or whatever Then I use the paint roller.I use dark gray in the default colors to shade or something. Then i still use dark gray with the paint roller to add small dots Then I use white with the paint roller to make lighter dots.Then I'm done. Sorry if this is confusing ^^"
