Not a big fan of garage doors as accent. Would paint them and the trim around them a color that closely matches brick even though that is not trim color on rest of house.

Thanks for responding. Not painting the brick, just want to change the cream trim color and the cream garage doors. I've been looking at Urbane Bronze by SW for the garage doors. Not sure about rest of trim color or if UB would look right with this color of brick.

I also don't like accent colors on garage doors(too large of mass). The "grayesh black"has a color in it,blue,red and green are common. First find the color within shingles then look for the same color in the multi-colored brick. From that color family,chose one you like when it's held against pure white. Paint doors,soffit and gutters that color(or that color with white mixed in if color is too dark) and trim with same paint with a small amount of pure black mixed into it if color is too light. That's one way of getting it right,there are others.

Sherwin Williams(one I use) and probably other real paint store web sites have a section where a person can download a picture(garage/house/room) and apply colors as they see fit. This is really the best way I know to DIY a paint color choice.
