7 Colors Designers Say Instantly Make a Home Look Cheap – And What To Definitely Use Instead

Color has the power to completely shape how a space feels – and crucially, how expensive your home looks. The difference often comes down to nuance: undertones, saturation, and how a shade interacts with natural light.

While no color is inherently ‘wrong,’ designers agree that certain tones can unintentionally make a space feel flat, harsh, or overly mass-produced. Highly saturated hues, stark contrasts, and overly clean pigments tend to lack the depth that gives interiors a layered, lived-in quality.

Instead, designers consistently favor complex, slightly muted shades to make a house look expensive – colors with earthy undertones or softness that evolve throughout the day. Below, color experts share the tones they tend to avoid and the elevated alternatives they turn to instead.

1. Non-Earthy Greens

Green is often seen as a safe, nature-inspired choice – but not all greens bring the same sense of ease. Interior designer Harriet Sale notes that many people gravitate towards cleaner, brighter greens, but without any earthiness, these shades can feel slightly artificial. ‘One of the biggest mistakes people make is choosing very clean or bright paint colors,’ she says, which can leave a room feeling ‘flat, harsh or slightly mass market’.

Harriet instead favors what she describes as ‘dirtier’ or muddier greens – tones with subtle olive, moss, or brown undertones that shift gently with the light. Hattie used Light Olive Green by Edward Bulmer in a recent barn conversion project to soften the feeling of a newly built space and create interiors that felt ‘grounded, settled and as though they had evolved naturally over time’. With its soft, chalky quality, the shade moves between olive, moss, and something almost stony depending on the light, creating a relaxed, timeless backdrop. As Harriet notes, ‘the best colors are the ones that feel as though they’ve always existed in the room’.

2. Fluorescent and Overly Saturated Hues

Bright, fluorescent tones can feel energetic, but they often overwhelm a space rather than enhance it. Interior designer Chizitera Pennington explains that ‘fluorescent colors demand a lot of attention and don’t easily give space for personal treasures and craftsmanship to shine,’ which can make a room feel less considered and ultimately less elevated.

Softened versions of bold colors – think ochres, clay tones, or sun-washed yellows – create a much more refined foundation. Chizitera points to shades like India Yellow and Marmelo by Farrow & Ball as perfect examples – earthier interpretations of brighter hues that feel confident rather than overwhelming. ‘Any color in a muted, earthy tone provides a solid foundation for a room,’ she says, allowing art, furniture, and personal details to shine.

3. Flat, Primary Blues

Blue can be one of the hardest colors to get right in a space – it can either feel calming and elevated or cold and slightly clinical, according to interior designer Ailsa MacConnell of Studio Mac. ‘Colors like this often have a flat, primary undertone, meaning they don’t interact particularly well with light.’ Without that complexity, the shade can feel one-dimensional with none of the tonal variation that creates visual interest.

Instead, Ailsa suggests turning to earthier, more nuanced blues, such as Cerullian Blue by Edward Bulmer. Unlike flatter tones, this shade has a soft, chalky undertone and is rich in natural pigment, allowing it to absorb and respond to light beautifully. The result is a color that shifts subtly throughout the day, adding depth and movement to a room.

4. Ultra-Bright, Cool Whites

Some of the most popular modern white paints are also the most deceptively difficult to use well. New York-based designer Lauren Carlucci points to Chantilly Lace by Benjamin Moore – ‘a crisp, pure white with slightly cool blue undertones’ – as a key example. While undeniably beautiful, she notes that ‘beautiful does not always mean right.’ The challenge lies in its clarity. ‘Chantilly Lace tends to expose what a room is missing rather than enhance what it already has,’ Lauren explains. In spaces with warm woods, brass, or natural stone, it can feel cool and slightly detached, even competing with the materials it’s meant to support.

Lauren recommends Dimity by Farrow & Ball, ‘a warm white with the palest blush undertone that shifts beautifully throughout the day’. Its subtle warmth creates a more cohesive, composed feel, allowing surrounding materials to sit in harmony.

5. Stark, Brilliant Whites

While similar in theory, stark whites pose a different issue – particularly in homes with softer natural light. ‘A very stark, brilliant white can often make a room feel flat and slightly cold,’ says designer Hattie Hansard of Joanna Wood Interiors. She adds that it can make interiors feel ‘developer-led or temporary,’ while running the risk of stripping away warmth and making architectural details appear harsher.

Hattie’s alternatives include Slipper Satin and Joa’s White by Farrow & Ball, both of which offer a gentler, more enveloping quality. These tones respond beautifully to shifting light, creating a calmer, more timeless feel that works effortlessly with natural materials and traditional details.

6. Cool-Toned Grays

Once a go-to neutral, cool-toned gray has quickly fallen out of favor among designers. Los Angeles-based designer Kim Lapin says she ‘especially avoids icy grays,’ explaining that they can make a space feel ‘flat, cold, and lifeless’. Often associated with more generic, overly sterile interiors, these shades can feel uninviting even when styled well.

In their place, Kim favors more grounded neutrals – shades that feel connected to natural materials rather than synthetic or overly polished finishes. Colors like Shoji White by Sherwin-Williams, Revere Pewter and Swiss Coffee by Benjamin Moore have a slightly weightier, more tactile quality – rather than sitting flat on the walls, these tones work in tandem with wood, stone, and textile.

7. In-Between Pinks

Not all soft colors feel calming – some can read as uncertain or indecisive. Designer and author Libby Cameron points to shades like Hummingbird by Benjamin Moore, a muted pink paint that sits somewhere between blush and mauve. The issue, she suggests, is not softness itself but a lack of clarity: tones like this can feel ‘neither one thing nor the other,’ which can leave a space looking unresolved.

If you’re drawn to pink, Libby recommends opting for something more defined, such as Ballet Slippers by Benjamin Moore – a true, pale pink that feels calm and flattering without ambiguity.

Ultimately, creating a home that feels considered comes down to nuance. The most successful schemes rely on subtle shifts in tone – colors with the right undertones, a sense of balance, and an awareness of how light moves through a space. Rather than relying on stark contrasts or overly perfect finishes, designers tend to favor palettes that feel cohesive and gently varied. It’s this interplay, between materials, color, and light, that gives a room its sense of ease and longevity. Even the smallest adjustment, whether warming up a white or choosing a more grounded green, can transform how a space is perceived.
