Beyond the Brush: What Millions of Paint Samples Reveal About America’s Changing Walls

For generations, the narrative of interior design trends has been dictated from the top down. Major paint manufacturers, color forecasting agencies, and prominent interior designers traditionally declare the definitive "Color of the Year" long before the average homeowner ever picks up a paintbrush or visits a local hardware store. These sweeping proclamations—ranging from moody navy blues to ethereal pastel greens—often create the illusion of a synchronized national aesthetic. However, these curated selections reflect intended directions rather than proven realities. A significant blind spot has long persisted in the industry: the gap between what people claim to love in a marketing campaign and what they actually test on their living room walls.

To bridge this analytical divide, the peel-and-stick paint sample platform Samplize has compiled and released its inaugural American Paint Color Report. Rather than relying on post-purchase sales data, which only captures a consumer’s final destination, this unprecedented study examines the crucial exploratory phase of interior design. By analyzing millions of paint samples ordered across the United States during the first six months of 2024, 2025, and 2026, the report offers a microscopic look at consumer decision-making. The comprehensive dataset spans industry heavyweights Benjamin Moore, Farrow & Ball, and Sherwin-Williams, providing a rare window into the comparative psychology of homeowners evaluating competing shades side by side before committing to a gallon of paint.

Decoding the Consumer Shortlist

The value of analyzing paint sampling behavior lies in its ability to reveal the messy, experimental middle ground of home renovation. According to Makenna Lutz, partnerships lead at Samplize, observing the sampling stage yields three distinct insights that traditional sales metrics miss: the full shortlist a consumer actually weighed, which specific colors were tested in direct competition against one another, and how those shortlisted options span across competing paint brands.

When homeowners order physical peel-and-stick samples, they are rarely operating in a vacuum. They are taping squares of color next to crown molding, observing how morning light shifts across a taupe versus a gray, and testing the emotional resonance of a bold red against a muted neutral. By aggregating millions of these individual shortlists, the Samplize report moves past anecdotal trend-spotting to map a clear statistical evolution in American taste. The data outlines a decisive departure from the cool-toned minimalism that dominated interior design throughout the 2010s, charting a methodical, multi-year migration toward warmth, depth, and earthy complexity.

The Great Warming: A Shift in Color Temperature

The most prominent finding across the multi-year dataset is a sweeping and accelerated preference for warm color palettes. Over the tracked three-year period, warm colors grew nearly three times faster than cool colors. By the midpoint of the study, warm tones accounted for a commanding 69.4% of everything tested on the platform, climbing substantially from 64.3% just two years prior.

This thermal migration is further underscored by the composition of consumer shortlists. Half of all American shortlists analyzed contained zero cool colors, a notable increase from the 43% recorded at the onset of the study. Homeowners are no longer simply hedging their bets by mixing slate grays with creamy whites; they are actively curating entirely warm palettes from the very beginning of the design process.

Counterintuitively, this warming trend has not manifested as a retreat into safe, feather-light pastels or airy ivories. A common assumption among market analysts was that a warming interior landscape would naturally skew toward lighter, brighter spaces to maximize perceived square footage and light reflection. The empirical data, however, tells a different story.

"The genuine surprise was in the split by depth," notes Lutz. "We expected the warming to show up as lightening—it didn’t. Warm outgrew cool at every depth, and the deepest warm tones grew fastest of all, roughly six times faster than deep cool tones."

This revelation challenges the long-held design dogma that dark interior colors must inherently carry cool undertones to remain sophisticated or modern. Instead, Americans are increasingly finding drama and elegance in deep, enveloping warm hues.

The Rise of Deep Warmth and Earthy Neutrals

Examining the extremes of the spectrum highlights this appetite for depth. At one end of the design spectrum, soft blush-toned plasters and warm creams are experiencing sustained traction. Products such as Farrow & Ball’s Setting Plaster, Benjamin Moore’s Proposal, and Sherwin-Williams’ Malted Milk reflect a desire for tactile, human-centric softness that mimics natural building materials.

Simultaneously, at the opposite end of the spectrum, deep and dramatic warm hues are surging. Benjamin Moore’s Classic Burgundy—one of the darkest and most saturated colors included in the research—grew at a pace comparable to the lightest pastels in the study. This indicates that homeowners have not lost their appetite for moody, high-impact interiors; rather, the underlying temperature of that drama has shifted away from charcoal blacks and navy blues toward rich, wine-soaked reds and saturated earthen bases.

This shift toward earth-bound palettes is equally apparent in the explosive growth of brown shades. Brown families grew faster than any other color category in the dataset, expanding from appearing in 9.2% of shortlists to capturing 13.4%. Crucially, this resurgence is not being driven by the glossy, hyper-saturated chocolates or rustic terracottas of past decades.

Instead, the growth is powered by sophisticated, muted hybrids. Sherwin-Williams’ Warm Stone and Urbane Bronze, Farrow & Ball’s London Clay, and Benjamin Moore’s Smokey Taupe represent a nuanced middle ground. These are greiges, warm grays, and stone-like neutrals that bridge the gap between historic brown and modern minimalism, offering a grounded backdrop that feels both contemporary and timeless.

Green Establishes a Permanent Foothold

While warm neutrals and earthy tones dominate the trajectory of the data, the report also highlights the maturation of green within the American interior landscape. Green has officially transitioned from a fleeting trend into a permanent fixture of the domestic palette.

After experiencing a sharp surge in popularity in preceding years, green has successfully held its elevated ground. Today, it appears in 34.6% of all consumer shortlists. Rather than leaning heavily into a single shade, the sampling data shows a diverse appreciation for the botanical spectrum, with homeowners simultaneously weighing pale sages, muted mosses, and deep, moody forest greens. Green functions increasingly as a neutral in modern design, bridging the psychological gap between the natural outdoors and interior living spaces.

Behavioral Patterns: The Decisiveness of Temperature

Beyond individual shade preferences, the Samplize dataset offers fascinating insights into consumer behavior and decision-making psychology. The data reveals that temperature consistency plays a massive role in how homeowners curate their spaces.

Two-thirds of all analyzed shortlists contained colors from strictly one temperature group. Specifically, half of all shortlists were entirely warm, while only about a third of consumers mixed warm and cool shades during the sampling phase. This suggests that homeowners generally possess a clear intuitive vision of their space’s desired emotional temperature before they even order samples, rarely second-guessing themselves by cross-shopping stark cool tones against rich warm hues.

Furthermore, there are early indications that this warming palette is becoming progressively more chromatic. While neutrals continue to anchor the market, pink and red represent the fastest-growing color families from smaller baseline starting points. When paired with the data showing that the "warm-and-deep" classification was the fastest-growing combination of temperature and depth, it becomes clear that consumers are becoming bolder in their application of warm color theory.

Implications for the Design Industry and Future Trends

While three years of sampling data cannot definitively predict the exact shade of every American wall for the remainder of the decade, it provides an invaluable empirical barometer of cultural mood. The data confirms that contemporary interior design is moving past the clinical, cool-gray neutrality that defined the post-recession architectural aesthetic.

The shift is not merely a lateral move toward lighter, quieter spaces. From soft, tactile plaster pinks and weathered stone-greiges to deep burgundy reds, American homeowners are actively exploring the full spectrum of warmth. As paint manufacturers and designers look toward future collections, the message from the consumer sampling stage is unequivocal: the future of home decor is warm, deep, and unapologetically grounded in earth-inspired complexity.
