Mountain Air vs Cotton Ball

Mountain AirDuluxvsCotton BallJotunΔE 2.4Subtle difference

Where Mountain Air belongs to Dulux's range, Cotton Ball is a Jotun color. Mountain Air reads as green-white, while Cotton Ball reads as beige-yellow — two distinct hue families, not close cousins. Mountain Air (LRV 88) reflects noticeably more light than Cotton Ball (LRV 85), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Both lean warm, so they'll behave similarly in mixed or changing light conditions. At ΔE 2.4, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

Mountain Air vs Cotton Ball in Real Spaces

2 real rooms side by side. Mountain Air and Cotton Ball are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.

Living Room

In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.

Kitchen

In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

Digital color is approximate.

Before committing to either color, test physical samples in your own space under the light you actually live with.
