The Peugeot 308 III, since its launch in 2021, offers a deliberately narrow color palette. Grays hold a special place: they represent the most chosen shade category for compacts in Europe, according to Axalta’s Global Automotive Color Popularity report (2024 edition). For the 308, this translates into several distinct references that, despite their apparent closeness, produce very different renderings depending on the light, finish, and body type.
Gray paint codes for the 308 III: what the configurator doesn’t always show
The online Peugeot configurator displays 3D visuals that smooth out the differences between shades. On a screen, the difference between a Gris Artense (code KCA) and a Gris Aluminium (code EZR) may seem subtle. In real conditions, the gap is striking.

The Gris Artense leans towards a medium gray, quite strong, with bluish reflections under natural light. The Gris Aluminium, lighter and brighter, is closer to a classic silver. Both shades are metallic, but their glitter granularity differs, which alters the perception of depth of the bodywork.
To explore the different shades of gray for the 308 with their respective paint codes, one must also consider a recent phenomenon: Peugeot has started to streamline its gray palette starting from the 2024 model year. Some less demanded metallic shades have been removed from the configurator in favor of hues that are better valued in the used car market, particularly medium grays like Artense.

Light gray or dark gray on the 308: the impact on the silhouette
A light gray like Aluminium visually widens the silhouette of the car. On the 308 sedan, whose lines are already quite taut, this effect can soften the side profile. On the SW estate, a light gray tends to accentuate the length of the vehicle.
In contrast, a dark gray tightens the volumes. It deepens the bodywork edges and highlights the play of light on the hood and side ribs. The 308 III, with its frameless grille and fang-like headlights, gains character with a dark shade.
The finish also plays a direct role. On high-end versions (Allure pack or GT), the chrome inserts and larger diameter wheels contrast more with a dark gray. On a base trim, a light gray better masks the absence of decorative elements.
Resale and depreciation: is gray still a safe choice for the 308?
Gray is often presented as the most neutral color, one that protects resale value. This claim deserves nuance.
The data from the Axalta 2024 report confirms that gray and silver shades still dominate preferences in Europe in the compact segment. A gray 308 will statistically find a buyer faster than a red or green 308, simply because the pool of potential buyers is larger.
On the other hand, this popularity has a downside: the supply of gray 308s in the used market is abundant. When many sellers offer the same shade, the buyer’s negotiating power increases. A less common color, like Rouge Elixir, can in some cases better withstand depreciation because it is rarer in listings.
- A medium gray (like Artense) positions itself as the best compromise: neutral enough to appeal to the majority, yet distinctive enough not to blend into the mass of silver grays
- A light gray (like Aluminium) maximizes raw resale ease but faces stronger direct competition on used platforms
- A very dark gray, if listed in the catalog, appeals to a more targeted audience and can create a slight rarity effect
Field feedback varies on this point: some professional sellers report that the exact shade of gray matters less than the condition of the bodywork at the time of the transaction. A light gray with visible micro-scratches loses more than a well-maintained dark gray.
Everyday maintenance: not all grays get dirty in the same way
The question of maintenance clearly separates light grays from dark grays. A Gris Aluminium tolerates road dust and lime stains after washing much better than a dark gray. The micro-scratches from washing, especially those caused by automatic station rollers, remain almost invisible on a light gray.
On a dark gray, each visit to the station potentially leaves visible marks in direct sunlight. Owners of 308s in dark shades often turn to hand washing or ceramic treatment to preserve the appearance of the bodywork.
The hybrid or electric motorization factor
On plug-in hybrid versions and the electric e-308, dark shades absorb more heat in summer, which can strain the air conditioning and, in turn, slightly reduce electric range. The available data does not allow for precise quantification of this gap on the 308, but the physical principle is documented across all electrified vehicles. A light gray reflects solar radiation better.
Gray 308 sedan or SW estate: the shade looks different
The visible body surface differs significantly between the sedan and the SW estate. The estate exposes a larger lateral surface and an elongated roof, which amplifies the effect of the chosen shade.
A metallic gray on the SW estate produces longer, more stretched reflections. The perception of color changes depending on the angle of observation. On the more compact sedan, the gray appears more uniform and denser because the surfaces are shorter.
For buyers who hesitate between sedan and estate, seeing both versions side by side in the same gray shade at the dealership remains the most reliable method. Online photos, even in high resolution, do not capture the depth of the metallics.
Ultimately, the choice of gray for the 308 depends on a trade-off between visibility of defects, effect on the silhouette, and positioning in the resale market. No shade of gray is objectively superior to the others: each responds to different uses and sensitivities.
