Choosing exterior house painting colors is the biggest design decision in a repaint, and it is the one you will live with for years. The right palette works with your roof, your stone or brick, the strong Idaho sun, and the rules of your neighborhood, not just with a swatch you liked online.
In short: start with the parts of the house you cannot change, like the roof and masonry, then choose a body color, a trim color, and one accent for the front door. Test large samples outside at different times of day, and check your homeowners association guidelines before you buy paint.
Start with what you cannot change
Your roof, stone, brick, and even the color of your driveway set the starting point. Sherwin-Williams advises homeowners to consider the colors in the roof, masonry, doors, and railings, because they will influence the exterior color choice.
- Roof: a warm brown roof pairs better with warm whites, tans, and greige. A charcoal or black roof works with cooler grays, blues, and crisp whites.
- Stone and brick: pull the body or trim color from a tone inside the stone, not from the brightest piece in it.
- Landscape: sagebrush, dry grasses, and mature trees around many Treasure Valley homes favor earthy, muted colors over very saturated ones.
Build a simple body, trim, and accent scheme
When choosing exterior house painting colors, most homes look best with three: one for the body, one for the trim, and one accent. The body color covers the most area, so it sets the overall mood. The trim outlines the windows, fascia, and corners. The accent goes on the front door or shutters, where a bolder color can stand out without overwhelming the house.
| Scheme | Body | Trim | Accent |
|---|---|---|---|
| Classic | Warm white or cream | Same white or slightly brighter | Black or deep navy door |
| Modern farmhouse | White | Black or charcoal | Natural wood door |
| Earthy | Greige or taupe | Off white | Deep green or rust |
| Contrast | Charcoal or dark gray | White | Warm wood or brass |
| Soft color | Muted sage or blue gray | Off white | Black |
How the Idaho sun changes exterior colors
Exterior colors usually look lighter and brighter on the house than on a small chip, because the light outside is much stronger than indoor light. In the Treasure Valley, high summer sun and long, clear days make this effect even more noticeable.
Two practical rules help. First, if you are between two shades, the slightly darker one usually reads closer to what you expect once it is on the siding. Second, very dark body colors absorb more heat on sun facing walls, which affects how the paint ages, so it pays to use a quality exterior product and plan the work around the weather. Our guide to exterior paint temperature in Idaho explains how heat and cold nights affect the paint itself.
Test exterior paint colors the right way
- Pick two or three finalists for the body, not ten.
- Paint large sample boards, at least two feet square, instead of looking at small chips.
- Place them on different sides of the house, including a sunny wall and a shaded one.
- Look at them in the morning, at midday, and in the evening.
- Hold the trim and accent samples next to the body sample, so you judge the scheme together.
Shaded walls make a color look darker, and full sun washes it out. Seeing both before you commit avoids the most common regret: a color that looks great on one side of the house and wrong on the other.
Check your HOA before you buy paint
If your home is in a neighborhood with a homeowners association, read its architectural guidelines before you choose. Many associations require approval for exterior color changes, and some publish an approved palette. Submitting your colors early keeps the project on schedule.
Colors that help resale and curb appeal
If you may sell in the next few years, neutral exterior house painting colors, with crisp trim and one confident accent, are the safest choice because they appeal to the widest range of buyers. Save bold body colors for a home you plan to keep, and express personality through the front door, shutters, and landscaping instead.
How color fits into the full exterior project
Color is only as good as the prep underneath it. Washing, scraping, repairing trim or siding, and priming bare wood come first, and they decide how long the new color will last.

Frequently asked questions about exterior house painting colors
How many colors should a house exterior have?
Most homes look best with three exterior colors: a body color, a trim color, and an accent for the front door or shutters. Some houses add a fourth for a garage door or a separate siding section.
Should exterior paint be lighter or darker than the sample?
Exterior colors usually look lighter on the house than on the chip because outdoor light is so strong. If you are between two shades, the slightly darker one often ends up closer to what you pictured.
How do I choose a house color that goes with my roof?
Match the temperature of the roof. Brown or warm roofs pair with warm whites, tans, and greige, while gray, charcoal, or black roofs work with cooler grays, blues, and crisp whites.
What exterior colors are best for resale?
Neutral body colors such as white, greige, soft gray, and taupe, with clean trim and a single accent color, appeal to the most buyers and are the safest choice if you plan to sell soon.
Do I need HOA approval to change my exterior paint color?
Often, yes. Many homeowners associations require approval for exterior color changes, and some provide an approved palette. Check your association’s guidelines before buying paint.
Do dark exterior colors fade faster?
Dark colors on sun facing walls absorb more heat and tend to show fading sooner than lighter colors. Using a quality exterior paint and proper prep helps any color last longer.
What are good exterior house paint colours for Idaho?
Earthy neutrals like greige, taupe, and warm white, along with muted greens and blue grays, tend to suit Idaho’s landscape and strong sun. Always test samples on your own walls first.
