I'd lean Sky Blue for a street food concept. The cool tone makes the warm food photography pop, while the gold sits very close to the colors already in the dish. Curious which one the client picked?
Keep the orange as the only hot color when you wrap the screens in the green. If the fields, the photo, and the button all go smoky, the Sign In loses the place it had on B. The green should be the room. The orange stays the action.
