I like the black. To be honest I did not notice the black railings and door until the picture with the black garage door!

Nor did I.

And I thought "they all look good... What am I voting on again??" I had to go back and read the post over lol.

Slight edge to grey over black for me, but a little darker grey would be my preference.

If that door faces south or west and you paint it black (or any dark color), you'll have even more angst when it overheats and warps.
