I would not rely on computer color representation to make your decision or to get others' opinions, as every monitor shows color differently. I have my monitor calibrated for professional graphic design work, and yet their copper penny color sample looks dingy pink. Copper has many color overtones, highlights and shadows and varies so much according to daylight vs. indoor light, time of day and surrounding colors. For starters, see if you can get an actual sample. Second look at photos of copper, both interior and exterior (Houzz is a good place). (These, too, are not exact replicas of actual color -- you're looking for general ideas.) Once you've narrowed your colors down a bit, get some large color swatches and see what looks good in your light and with the surrounding environment. For example, mossy green is usually a good companion with copper, but if you are surrounded by greenery, this may not be the best shade. Are you out in the sun or shaded by a grove of trees? In addition to house style, consider your context. A metal roof often suggests a country setting, but is that true or are you on a city lot or in a development with houses close by? When you have it narrowed down your choices, post a photo of your copper and large paint swatches here to get opinions. (Note: the colors will still look different from reality, but hopefully they will be altered to a similar degree.) When you have three contenders, paint large areas on several sides of your house, preferably at the corner where you can see surrounding trees and neighbor houses.

I googled your paint color and two additional colors were on the same page. Any of these would look nice on your place; it's just a matter of how dark you want to go.

Love pictures 2 and 3, and the idea of black light fixtures. Are you painting the shutters or replacing them? If you are replacing them, take the old ones off and look at your house with no shutters. Your house may look larger without shutters, ours did. The current shutters look too narrow for the windows (you have nice size window). Each shutter on a window should be half the width of the window, so if they're closed they would cover the window. I know most shutters are totally decorative, but the size and proportions should be the same as if they were functional. You may not have room on the main house for larger shutters, but you could put larger shutters on the area with partial rock wall. To determine the color that would look best, take a couple off and paint them. Be sure what color you choose looks good with the rock on the front of the house.

I would not do warm colors on this house. you have a very cool blue/gray silver roof. and the house is more contempary. You picture is very small and it's hard to photoshop anything, but here's a more streamlined darker garage door w/windows, and your door is painted a charcoal. for the body you could try one of the cool, slvery blue tones. wrought iron for the doors.
