I don’t see any brick except the foundation? Is there more not shown?

I think you pretty much have to match the buff/yellow brick to avoid looking like three different houses attached together.

There is a brown brick along the bottom and a terracotta brick for most of the exterior walls.

Unfortunately the colorbond paperbark and cream are too yellow as the bricks are more pink orange than yellow.

We were considering matching the warm grey in the stone?

I wouldn’t add another color. Already way too much going on. Try matching the orange brick and then do nice foundation planting to hide the dark brown bricks. Additional landscaping is a great way to distract the eye from less desirable elements.

Agree with matching paint to brick.
