I really like stucco, it is a red tile roof combination, my friend are having Stucco on our house. They are harsh in winter as well as wet in summer. They are having no problems with this roof siding, no difficulties are arrive in putting siding over stucco.

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.

For new buyers, keep the lakeside vibe going. Here is a great lakehouse, imo. The green used is BM's Crisp Romaine. Do remove the shutters and upgrade/upsize the lantern over the entry. Then tackle the landscaping. You want it to look self-maintaining. People moving to the lake don't want to see a bunch of chores waiting for them when they drive up to the home. They may not have a green thumb, so don't let the landscaping scare them away.

That house could look good in almost any color. White, off white, yellow, green and darker colors too. Generally a darker roof like charcoal will work with more colors. Trim color is also important, and will make a big impact on the overall look. Trim can complement instead of contrast. There are plenty of images here on houzz and other sites to give you some ideas. You can also have the house modeled in software and apply various colors and materials to see how they would look. Read down in this thread for an example. https://www.houzz.com/discussions/4710835/help-with-exterior-colors
