Working with what stays
Keep the gable shapes readable
The Craftsman example has several roof planes, two siding textures and a covered porch. A dark body and roof can reduce their visible separation. Try a softer trim around the gables before adding more accent colors.
Watch shaded entrances
A porch already lowers the apparent brightness of the entry. Compare the front door and surrounding trim in that shaded area, rather than choosing from the sunlit upper siding alone.
