You could do gray or blue, but not too baby blue but a steel blue/gray.

sage green cream or white trim.

love your topiary and azaleas.

I LOVE the blue suggested by “houssaon” with bright white trim. No one will notice the brown roof.

I feel all of the colours you've suggested will result in a look quite similar to what you have already - as well as the house next door. I do love the blue suggested by houssaon, above. Alternatively, we have a dark brown roof and used a fairly dark brown siding. We used extra wide white trim to offer some relief from the dark siding. You'll notice in houssaon's picture, the trim is quite substantial. It makes a huge difference. Your yard is lovely as is your fence. Good luck!

Some options

Wow this is so cool! My favorite are 1,2 & last one. The blue is nice too and my 17 year old son suggested this color. I think it would definitely stand out in my neighborhood of cream, beige and tans homes. We have a paved walkway in harvest blend so we were also thinking of doing a stone wall only on the front portion of house which is an enclosed porch just to break up color of house.
