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.

Love your house! Your roof, brick, and flagstone are all warm colors, and the roof and the flagstone have some intensity of color. They need a color with some weight to it, just enough to stand up to them LOL, not enough to challenge them. Look at some samples in a deeper sage color or a silvery/bronzy/greeny color. If it will go with your flagstone, it will go with the house. Have fun!

what if you brought in some terra cotta pots w/the jute/black mats/rug? maybe did a birdbath, southwestern style, in the middle ? suround it w/some native plants? so many cool ways to add some color right there. bubbling urn, terra cotta, lots of boulders/pebble rock, container plants, I'd prob do something like these rocks, the bubbling urn or a colorful birbath, some mexican pebble rock up aginst the cobble, a few plants in a some colored pots. or something simple like this with a little pathway, the bench, some solar lights or, a little bistro table chairs i'd layer something like this on top of the larger jute rug. how about a place to sit? love these two colors (the wood) w/the terra cotta, black and the aqua (and copper) (oh, but you don't like this color, right? w/the black and copper, I think it's a nice addition. use the cobalt if you prefer) a southwestern style bench up against that part of the wall (you could always do this bench in the color that you like. ) a sun on the wall behind it, a copper southwestern style door handle, and pots to match? maybe a southwestern door mat. These are just thrown together. you could pick better colors and styles. gave you the wood bench here w/the cobalt pot. love these colors

Some of the paint company websites will substitute their paint colors into your photos. But I use Photoshop when I do mock-ups here. It's nontrivial.
