Welcome to ECF!
Basic black goes with anything
Nah, can't help you with your color choice, but any will look fine with the PT3 mini. It's a nice topper, works well and looks good on that form factor. Make sure you get some extra
coils / heads with it, as they do gunk up. (They can be cleaned, dry burned and revived, but just starting out, it's easier to just pop in a new one when needed. Don't need too steep a learning curve at first
)
You can set the VV3 to either VV or VW mode. They are two different ways to control how much power goes to the coil, therefore how much vapor you get. Different juices (flavors) may taste better at different levels. Many like VW mode, which will keep the same power level to the coil no matter what the resistance of the coil is. (Within design specs, of course.) So you get the same
vape when you change toppers.
In either case, just start at a low setting and work up in steps until the
vape starts to taste off, then back off a step or two and enjoy
