OP hasn't shown the front door. The pedestrian door to the garage should be painted the siding color to blend into the siding. Having it a different, prominent color will cause confusion to guests and not enhance the house at all. The design of the garage doors does conflict with the design of the house portion we can see.

We recently painted our house, including the siding, all the trim, and the front door. The siding color was previously a light shade of gray, and the front door was black. We were hoping that the new color scheme would cause the garage to recede while also pulling attention to the front door (which is always in the shadows due to the large tree in front, the angle of the house, and the porch roof). We went ahead and painted the garage door trim to match all the other trim. I am sort of feeling that it looks too busy with that garage door trim causing lines to pop out across the front expanse of the garage. Maybe there's just not a good way around it; the original house design, combined with the large tree, really makes the garage prominent. If we painted the garage door trim the same color as the siding, would that look odd? Would it make the garage look too imposing as a wall of nearly solid green? Should we accept the fact the garage is prominent and consider getting nicer doors that we might paint white?

I would make the garage door match the garage siding color so that it will not stand out and be highly noticeable. There's nothing particularly appealing about a garage door. I would avoid making the garage door a highly contrasting color. Some folks like the trim to contrast with the siding; some folks like the trim to match. Your call!
