What exterior paint colour lasts the longest before fading on homes in New Brunswick?

Lighter, neutral colours with earth-based pigments — whites, soft greys, warm beiges, and muted greens — fade the slowest on NB exteriors. Bright, saturated organic pigment colours (particularly reds, yellows, and some vivid blues) are the fastest to fade under UV exposure.

Colour fade on exterior paint is driven primarily by UV radiation, and NB gets significant summer UV despite its northern latitude. South- and west-facing walls take the most punishment — they receive direct afternoon sun through the summer months, which is when UV intensity peaks. The speed of fading depends on both the colour’s pigment chemistry and the quality of the paint’s UV-resistant binders. Understanding this helps you choose colours that will still look great after five or seven years of NB winters and summers.

The most fade-resistant colours are those made with inorganic mineral pigments: titanium dioxide-based whites and near-whites, iron oxide-based earth tones (tans, taupes, warm browns, ochres, and terracottas), carbon-based blacks, and certain blue-green colours derived from mineral pigments. These pigments are inherently stable under UV — they do not break down chemically when exposed to sunlight the way organic pigments do. This is why a classic white or a warm greige house in Moncton still looks fresh after a decade, while a house painted in a vibrant red or clear yellow can look washed-out within three or four years.

The fastest-fading colours on NB exteriors:

• Bright, saturated reds — many red pigments are organic and highly UV-sensitive. If you love red, choose a deeper, more muted red-brown or brick tone (iron oxide-based) rather than a vivid crimson or scarlet.


• Pure yellows and oranges — organic yellow pigments fade quickly and can shift to a dingy cream or tan.


• Vivid medium blues — some synthetic blue pigments are less stable. Navy or slate blues tend to hold colour better than bright medium blues.


• Purples and violets — these often fade unevenly, shifting toward red as the blue component fades faster.

How to choose a long-lasting colour for your NB home:

• Look for exterior paints with fade-resistant or colour-lock technology on the label — Benjamin Moore Aura Exterior and Sherwin-Williams Duration Exterior both use advanced UV-resistant resin systems that meaningfully extend colour life compared to standard exterior products.


• Ask the paint store which pigments are used in your chosen colour — a knowledgeable store can advise on the fade resistance of specific formulations.


• For south- and west-facing walls that receive the most sun, lean toward lighter shades of your chosen colour or opt for an earth-tone neutral.


• Accept that all exterior paint fades over time in NB’s climate. The goal is to slow it down, not eliminate it. A premium paint’s UV-resistant binder makes a tangible difference — expect 7-10 years of good colour retention with Benjamin Moore Aura or Sherwin-Williams Duration versus 4-6 years with a budget exterior paint.

One final practical note for NB homeowners: dark colours absorb significantly more heat, which causes the paint film to expand and contract more aggressively through the seasons and accelerates the breakdown of the paint binder. In NB’s climate of extreme temperature swings, very dark colours on wood siding — while fashionable — require the highest-quality 100% acrylic latex exterior paint to hold up. If you are drawn to a charcoal or deep navy exterior, budget for premium paint and plan to repaint on the shorter end of the expected lifespan.
