Siding: West Coast #1671 / Trim: Vermont Slate #1673 / Doors & windows: Segivia Red #1288. These are the colors I wanted originally but ended up with "olive" or "army" green and terra cotta red....because it's so hard to get paint mixed to the right color in these stores out here in the country.
If you aren't sure what size of lantern is right for your porch, use the same rule of thumb as for picking an indoor chandelier: Add the length and width of the space. The number of feet in the sum is roughly the number of inches your fixture should be. For example, a 12-by-15 porch would hold a 27-inch lantern.
