Two weeks ago when John shared a post about the times we’ve made bad painting decisions, many readers asked for a follow-up showing side-by-side swatches to help identify undertones and choose more reliable wall colors.
Q: I have trouble telling which swatches have gray or brown undertones. Could you show swatches — one with a gray or brown undertone and one that’s more saturated? Seeing them side by side would help! – Aubrey
Q: Tip #3 about picking a muddier color surprised me. Colors often look different on screens, but I’d love to see color samples with explanations like, “We love this peacock blue, but it would be too garish on a wall. Instead, try this muted option to get a better effect.” – Heyruthie
Those were great suggestions, so we decided to let comparative swatches illustrate the point. Photos speak louder than words when it comes to undertones, so here’s a practical guide to choosing paint samples for larger surfaces like walls and doors.
On the left in the first example you see a bold teal that you might be tempted to use. On the right is Plumage, the actual color we used in our guest room. The swatch on the right appears grayer and more faded than the vivid option on the left, yet when applied to the walls it reads just as bold as we hoped.
Dark colors amplify significantly once painted on a large surface, so our rule of thumb is to start with shades that look a little muted or grayed on the swatch. Those tones typically deepen and become clearer in situ. For more about this guest room choice, see our earlier project notes mentioned in the original post.
Next, consider a bright pink accent. A small sample of a highly saturated pink can be tempting, but in a larger application such as a closet door it can verge on neon. We opted for a slightly muddier pink that looks faded in a tiny swatch but becomes vibrant and balanced when painted over a larger area. Small, intense swatches often translate to overwhelming color when used in quantity.
Another common challenge is aqua tones. A cheerful, Tiffany-style blue can be seductive on a small chip but overwhelming on an entire room. In our experience, a cleaner, brighter aqua often becomes blinding in large amounts unless the space has exceptional light. Choosing a softer aqua with gray-green undertones usually delivers a pretty, readable color without overpowering the space.
As a general guideline: clear, unfaded colors are great for small items — trays, side tables, lamp bases, or accent furniture. For doors, walls, and ceilings, we prefer muddier versions of the same color family so the hue remains stylish rather than aggressive.
Greens follow the same pattern. A vivid green can look fantastic on a piece of furniture or a vanity but may overwhelm an entire room. Muddier greens with sage or gray undertones often behave beautifully on walls, especially with wood trim or cabinetry. Those muted greens bring warmth and calm without tipping into cartoonish territory.
It can be surprising how a swatch that looks almost beige in your hand can read as a clear color on a painted wall. A muted swatch with wheat or gray tones can look neutral on the chip but becomes unmistakably green or blue across a larger surface. If you want a subtle, softly colored wall, look for lighter swatches that contain just a hint of the color rather than a pure, saturated pigment.
Quick note: Readers asked whether the muddier version of a color appears on the same swatch strip as the bright one. In our experience, the muddier counterpart is usually on a different swatch, so you may need to compare several strips and move across to find the grayer or deeper top colors, then slide down to discover the muted versions.
A final example is Dune Grass, a paint that can appear beige on a small sample but reads as a soft green on the walls. When you paint more of the surface, the green subtly reveals itself and creates a gentle, inviting color that pairs well with neutral finishes.
Because screens can misrepresent hues, the best approach is to bring several swatches home and observe them in your room’s light throughout the day. If you’re still unsure, buy a few small test pots and paint sample areas on the wall. Those inexpensive samples can prevent costly repainting later.
Lighting and room context matter a lot: a bold color that would overwhelm one space can be spectacular in a bright, lofted studio with lots of texture and neutral accents. So test your choices, consider muddier variations for large areas, and lean on samples to confirm your instincts.
Here are a few practical tips for saving money when buying paint:
- Consider “oops” paint — returned, premixed cans sold at steep discounts. Mixing a few cans can produce an inexpensive, usable color.
- Sign up for local paint store newsletters or follow their social pages to catch sales and special offers.
- Check big-box retailer promotions and paint brand discounts when planning a larger project.
- Using a store credit card sometimes provides instant savings at checkout; policies vary so ask in-store.
- Keep an eye on seasonal sales from major brands for significant discounts on gallons and supplies.
