Is there anyway I can darken my paint just a shade without having to go back to the paint store?

Yes, you can darken it but you will have little control. Most paint stores sell tinting colors you can try at home like lamp black but you'd be driving to the paint store to buy this stuff so maybe its best to ask the mixing guy at the store.
