Working with what stays
Follow the roof and window lines
The butterfly-roof example is organized around opposing roof planes and large glass panels. Let the body and trim comparison show those lines; avoid introducing color breaks that do not follow a visible surface change.
Use the entry as the smaller accent
The rust-red door and stone pier show how a small concentrated accent differs from a whole dark facade. Compare that with the charcoal ranch's wood entrance rather than repeating one accent treatment on both houses.
