Mammoth Mountain vs North Pole Blue
Both from Behr's palette. These are both blues, so the question isn't which hue to choose — it's where within blue to land. North Pole Blue (LRV 26) reflects noticeably more light than Mammoth Mountain (LRV 11), a difference of 15 points that becomes especially apparent in rooms with limited natural light. Both lean blue, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 21.2, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Mammoth Mountain vs North Pole Blue in Real Spaces
6 real rooms side by side. Seeing Mammoth Mountain and North Pole Blue in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Living Room

Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. North Pole Blue reflects noticeably more light off the walls, making the space read more open than Mammoth Mountain.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. North Pole Blue reflects noticeably more light off the walls, making the space read more open than Mammoth Mountain.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. North Pole Blue reflects noticeably more light off the walls, making the space read more open than Mammoth Mountain.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. North Pole Blue reflects noticeably more light off the walls, making the space read more open than Mammoth Mountain.
Kitchen Cabinets
