Color Samples and Help Choosing the Right Colors

Choosing paint colors can feel overwhelming. At Tri-Plex Painting, we help homeowners throughout Littleton, Denver, Lakewood, Centennial, Highlands Ranch, and Lone Tree feel confident before moving forward with their interior paint color selection.
Our color process may include:

Seeing the color in your home helps eliminate surprises and ensures you’re happy with the final result.
Choosing the right interior paint colors is one of the most important parts of any interior painting project. The right palette can make a home feel brighter, larger, warmer, or more modern, while the wrong choice can make even a well painted space feel off.
White Ceilings for a Clean, Bright Look
White ceilings remain the most popular choice in residential interior painting—and for good reason. A white or near-white ceiling helps reflect light, makes rooms feel taller, and keeps the space feeling clean.
Popular ceiling colors include:
- Soft whites with minimal undertone
- Slightly warm whites for homes with wood flooring
- Flat finishes to reduce glare and hide imperfections
Most homeowners choose a consistent ceiling color throughout the home for continuity.
Some great ceiling colors to choose from are:
- Sherwin-Williams Snowbound (SW 7004) – a soft, clean white that works with most wall colors
- Benjamin Moore Simply White (OC-117) – bright but not stark
- Sherwin-Williams Alabaster (SW 7008) – warm without yellowing
These shades reflect natural and artificial light, helping rooms feel larger.
Wall Colors: Neutral, Warm, and Livable
For 2026, homeowners are continuing to move toward warm, livable neutrals rather than stark grays. These colors work well in open floor plans and allow furnishings and décor to stand out.
Common wall color choices include:
- Warm off-whites and creams
- Light greige and beige tones
- Soft taupe's and muted earth tones
These colors provide flexibility and age well over time, making them a strong choice for long-term value.
Some popular wall colors are:
Sherwin-Williams:
- Accessible Beige (SW 7036) – warm, subtle, and pairs with many trim shades
- Repose Gray (SW 7015) – soft greige with gentle warmth
- Comfort Gray (SW 6205) – light and calm without feeling cool
Benjamin Moore:
- Revere Pewter (HC-172) – classic gray with warm undertones
- Edgecomb Gray (HC-173) – soft greige that stays light
- Classic Gray (OC-23) – quiet and elegant without feeling bold
These tones help open floor plans and connected living spaces work together visually.
Door and Trim Colors
White trim remains a favorite for interior painters and homeowners alike, especially when paired with neutral wall colors. It provides contrast and keeps spaces looking sharp and finished.
Popular trim and door choices include:
- Clean whites or soft whites
- Slightly warmer whites for traditional homes
- Satin finishes for durability and easy cleaning
For a more modern look, some homeowners opt for doors slightly darker than the trim for added depth.
Some customer favorite door and trim colors are:
Sherwin-Williams Pure White (SW 7005) – slightly warm and versatile
Benjamin Moore White Dove (OC-17) – soft, traditional white that performs well on trim
Sherwin-Williams Extra White (SW 7006) – brighter, more modern option
Accent Colors for Visual Interest
Interior Painted accent walls are still popular when used thoughtfully. In 2026, we’re seeing more subtle accents rather than bold contrasts.
Accent colors often include:
- Muted blues and greens
- Soft clay, terracotta, or earth tones
- Deep charcoal or navy in select spaces
Accent colors work well in living rooms, stairways, offices, and bedrooms when balanced with neutral walls.

Benjamin Moore Hale Navy (HC-154) – rich and timeless for a feature wall

Bathroom Paint Colors That Feel Clean and Calm
Bathrooms benefit from colors that feel fresh, relaxing, and bright—especially in spaces with limited natural light.
Popular bathroom colors include:
- Soft whites and light neutrals
- Pale blues and spa-inspired greens
- Light grays with warm undertones
Pairing the right color with proper ventilation and moisture-resistant paint helps maintain a clean look long term.
Top bathroom color picks:
Sherwin-Williams Comfort Gray (SW 6205) – gentle, not too cool
Benjamin Moore Palladian Blue (HC-144) – spa-like and soft
Sherwin-Williams Sea Salt (SW 6204) – soothing and works with white tile
Living Room Colors That Bring Spaces Together
Living rooms often connect multiple areas of the home, so choosing a versatile color is key. Neutral tones with warmth continue to dominate in 2026.
Popular living room colors include:
- Light greige and beige
- Warm off-whites
- Subtle earth tones
These shades allow flexibility with furniture, artwork, and accent colors.

Popular kitchen paint choices include:
- Soft whites and warm neutrals on walls
- Muted greens, blues, or charcoal for accent areas
- Light colors to complement natural or stained cabinetry
These palettes help kitchens feel inviting and timeless.

Protecting Your Home During Interior Painting

We know inviting painters into your home requires trust. That’s why at Tri-Plex Painting, protecting your space is a top priority on every interior painting project.
Protecting a home during an interior painting project is just as important as the quality of the finished paintwork. Homeowners looking for reliable interior painters want to know their floors, furniture, and personal belongings will be respected throughout the process. At Tri-Plex Painting, protecting the home is a standard part of every interior residential painting project we complete in Denver, Littleton, Highlands Ranch, Lakewood, Centennial, and Lone Tree.
Before any interior painting begins, our interior painters take the time to properly prepare each room. Furniture is carefully moved or grouped and fully covered, while floors are protected with clean drop cloths or floor coverings designed to stay in place during the project. High-traffic areas such as hallways, stairways, and entryways receive additional protection to prevent tracking or damage while work is underway.
All areas that remain in the space are protected as well. Windows, trim, outlets, hardware, and fixtures are neatly masked so paint stays exactly where it belongs. During interior residential painting projects in kitchens and bathrooms, countertops, cabinets, appliances, and plumbing fixtures are fully covered. When electronics such as televisions, speakers, or computers are present, our interior painters take extra care to shield them from dust and paint splatter.
Throughout the interior painting process, we maintain clean and organized work areas. Tools and materials are stored neatly at the end of each day, and walkways are kept clear so the home remains safe and livable. Many of our interior residential painting projects are completed in occupied homes, so minimizing disruption is always a priority.
Once the interior painting is complete, all coverings are removed, debris is disposed of, and the space is thoroughly cleaned so homeowners can immediately enjoy the finished results. This attention to detail is what homeowners across the Southern Denver Metro area look for when hiring professional interior painters and it’s why Tri-Plex Painting continues to be a trusted choice for interior residential painting. Our goal is to have you as a client for life!
Commercial Interior Painting

Protecting a corporate interior during a painting project requires planning, coordination, and attention to detail. Corporate offices, conference rooms, and shared workspaces often contain valuable equipment and must remain functional while improvements are being made. At Tri-Plex Painting, protecting the work environment is a core part of every commercial interior painting project we complete for corporate clients throughout Denver, Littleton, Highlands Ranch, Lakewood, Centennial, and Lone Tree.
Prior to the start of any painting, our team conducts a thorough walkthrough to understand the layout, workflow, and operational needs of the space. Furniture is carefully repositioned or grouped and fully covered, while flooring is protected with professional grade materials designed for high traffic commercial environments. Special consideration is given to hallways, entrances, and common areas to ensure safe and uninterrupted access during the project. The Tri-Plex Painting team also post "WET PAINT" signs throughout the project and remain in constant communication with the onsite contact. We believe that good communication is the key to success!
All fixed and sensitive elements within the space are protected with equal care. Windows, trim, fixtures, outlets, and hardware are precisely masked to maintain clean lines and prevent overspray (if a sprayer is in use). In conference rooms and executive offices, wall-mounted televisions, sound systems, whiteboards, and presentation equipment are carefully covered.
In corporate break areas and restrooms, countertops, cabinetry, appliances, and plumbing fixtures are fully protected before painting begins.
Throughout the project, we maintain organized and professional job sites that reflect the standards expected in corporate environments. Materials and equipment are stored neatly at the end of each workday, and work areas are kept clean so employees and visitors can move through the space safely. Many of our corporate interior painting projects are completed in occupied buildings, so scheduling, efficiency, and clear communication are always prioritized. We have found that these are the keys to a successful contract/client relationship and how our Tri-Plex Painting team has been successful in the Denver Metro area for over 36 years!
