You drive around and make a whole album of color combos you like. I thought picking a roof color was hard! House is even worse!
I go to a paint store. stand in front of the general color I want. close my eyes and put my finger blindly onto an exact swatch.
Are you in a Homeowner's Association?Check with your Board and Property Manager first. People have lost their homes after painting them the wrong color, and refusing to comply.
I think there are websites where you can upload pics of ur house and change the paint color. I know we did that with our roof.
