Photoshop can be used to convert line-art sketches into color "paintings." Here are three houses where I have done that. Different techniques have been used with each house to give it interest and individuality.
House #1
House #1 with blue sky. Usually painted architect sketches have an unpainted or white sky. Here I have added a very pale blue sky. I think it enhances rather than detracts from the image.
House #2
House #3
