We are adding onto our house and our vinyl siding will remain white..our new shingles are charcoal grey, pretty much black and I am now curious if

1.) I should modify garage doors to be black or white? I am afraid if they are white it will be one big white monster-no definition!

2.) Also unsure of gable ends-should I do same color of doors in vinyl or vinyl shakes for some contrast?

3.) considering some stone between the garage doors maybe 3 feet high?

Any opinions/thoughts are greatly appreciated!
