Choosing the right exterior colors for your post-frame building is one of the most important and exciting decisions you’ll make during the construction process.
After all, it’s the first thing people notice when they drive up to your property.
Some owners want their building to blend naturally into the surrounding landscape, while others want it to stand out as a bold centerpiece. Either way, thoughtful color choices play a major role in the final result.
In this guide, we’ll walk through practical tips to help you create a color palette that works for your property, your purpose, and your long-term vision.
Greiner Buildings has been designing and constructing post-frame buildings for customers in Iowa and Illinois for over 35 years. With more than 2,000 projects completed, we’ve helped customers choose exterior color combinations for everything from agricultural barns and machine sheds to hobby shops, commercial buildings, and Shome® homes.
7 Tips for Choosing the Best Pole Barn and Post-Frame Building Colors
Here are a few key reminders to point you in the right direction when picking your colors and help you avoid any expensive regrets five years from now.
1. Coordinate With Nearby Buildings. When selecting colors for your pole barn or post-frame building, it’s important to consider nearby structures such as homes, Shome®, garages, barns, or other farm buildings. Coordinating exterior colors can create a balanced and cohesive look across your property.
2. Think About the Natural Environment. Even if there are no nearby buildings, you still need to consider the surrounding landscape. Are there evergreen trees or crop fields nearby? Do you prefer your post-frame building to blend in or stand out?
3. Learn About Color Restrictions Before finalizing your exterior colors, check for any local color or design restrictions that may apply in your area. While these rules are less common today, some municipalities, counties, or homeowner associations may have guidelines for building appearance. A quick conversation with your local building inspector or zoning office can help ensure your project meets any requirements before construction begins.
4. Consider the Purpose of Your Building Before choosing exterior colors, take a step back and think about the purpose of your building. Is it an agricultural barn, a machine shed, a hobby shop, a barndominium, or a commercial building?
The function of the structure often influences the style and color choices.
For example, a working farm building may lean toward traditional, practical color combinations, while a barndominium, Shome®, or hobby shop may allow for more modern or personalized design choices.
5. Don’t Forget About Accent Colors Your roof and walls make up most of the exterior steel on your building. Contrasting or coordinating colors for trim, door panels, soffit, and wainscoting can create a combination you love.
6. Choose high-quality metal and paint. You should choose your pole barn metal and paint carefully so that it stands up well against the elements for years to come. Remember that the only thing between you/your interior and mother nature is often the metal panel. The paint is the first layer of protection that comes in direct contact with the elements 24/365. Greiner Buildings uses a variety of metal manufacturers depending on client perspectives including J MAC Metals, Central States, and McElroy Metals.
Our preference is to use a 26 gauge panel w/ G90+ galvanization and most importantly 70% PVDF resin-based paint. The heavy panel adds strength while the G-90 galvanization avoids edge-rusting. Since this article is about paint we’ll hone in on that topic further. PVDF resin based paints such as Kynar, Hylar, or Trinar (which are competing brands), are known for their superior capability to retain color – reducing fading and chalking over time. By far, PVDF’s counterpart SMP (siliconized modified polyester) paints are most common because they are cheaper. But they fade quicker and all that work you did to choose beautiful colors will quickly disappear as fading is very unattractive.
Take it from the experts at GB – use PVDF, it’s worth every penny!
Greiner Buildings also offers a 10 year edge rust warranty to help protect against premature edge corrosion.
Regarding warranties, most warranties in the industry are quite similar but be sure to understand what the metal manufacturer warranty actually covers. You’ll want to choose a reputable manufacture to protect you from defects such as chipping, cracking, etc.
7. Consider your energy efficiency needs. Color choice can also influence energy efficiency. Certain metal colors and coatings are designed to reflect sunlight and reduce heat absorption, which may help regulate interior temperatures. This can be especially helpful for buildings used as shops, storage spaces, or living areas.
If energy efficiency is a priority, ask us about reflective color options and coatings that can help improve thermal performance while still achieving the look you want.
How Many Colors Should You Choose for a Pole Barn or Post-Frame Building?
There is a wide variety of color schemes available for pole barns, but the most common are two-tone and three-tone combinations. Most buildings use one color for the sidewalls and another for the roof, with a third color used for trim. Often, the wainscot, windows, doors, and trim are coordinated with the roof color.
Start by thinking about your pole barn or post-frame building colors in three main categories:
- Metal wall siding color
- Metal roof color
- Trim color
However, if you prefer a single-color scheme where all building components are the same color, that’s an option as well.
There are also opportunities to incorporate four-color designs. Pole barn features such as overhead doors, walk-in doors, window trim, cupolas, and mansards now come in a wide range of colors, allowing you to add additional character and detail to your building. These features can take your building’s design to the next level visually. The choices are limited only by your imagination.
Regardless of how many colors you choose, remember that the goal is to make your building stand out against the landscape. Try to avoid matching the roof and sidewalls exactly. A little variation can go a long way.
Popular Pole Barn and Post-Frame Building Color Trends
Exterior color trends for pole barns and post-frame buildings continue to evolve. While personal preference always plays a role, certain color combinations stand out for their timeless look and versatility.
Some of the most common pole barn and post-frame building colors include:
• White
• Charcoal gray
• Smoke gray
• Burnished slate
• Beige and off-white tones
• Matte black
• Red
• Hunter green
• Brown
• Copper or bronze tones
The Modern Farmhouse Look: One of the most noticeable shifts in recent years has been the move from traditional red barns to modern white and black color combinations.
A black and white palette offers a clean, timeless look that works well for hobby shops, garages, barndominiums, and Shome® homes. White siding paired with black trim or window frames creates a modern appearance while still feeling warm and inviting.
Many owners also choose a matte black metal roof to complete the look.
Typical combinations include:
• White or off-white siding
• Matte black roof
• Black trim
• Natural wood accents
Dark Modern Buildings: Another growing trend is darker exterior palettes.
Common combinations include:
• Charcoal gray siding
• Matte black roof
• Black trim
• Dark bronze doors
Some buildings even use monochromatic designs where the entire structure is charcoal or black.
These darker palettes create a bold, modern appearance and tend to hide dirt and wear well.
Earth Tone Buildings: Earth-tone palettes remain extremely popular for agricultural buildings and rural properties.
Typical colors include:
• Burnished slate
• Brown
• Clay or tan
• Bronze
• Dark green
These colors blend naturally into farmland and rural landscapes while reducing visual contrast on large buildings.
Two-Tone Wainscot Designs: Two-tone designs featuring contrasting wainscot panels are also very common.
Examples include:
• Light siding with dark wainscot and roof
• Dark siding with lighter wainscot and matching trim
Wainscot designs help break up large wall surfaces while hiding dirt and wear near ground level.
Warm Metal Tones: Warmer metal tones are becoming more popular on modern barndominiums and high-end shops.
Examples include:
• Copper tones
• Dark bronze
• Weathered wood finishes
• Rust or corten-style metals
These are often paired with charcoal roofs, black trim, and natural wood accents.
Monochromatic Buildings: Some property owners prefer monochromatic designs where the entire building uses one primary color.
Examples include buildings that are entirely:
• Charcoal
• Black
• White
This creates a clean, modern architectural look.
Traditional Barn Colors: Traditional barn colors are still widely used, especially for agricultural buildings.
Examples include:
• Red with white trim
• Green with white trim
• Brown with tan trim
These classic combinations remain timeless for working farm properties.
