Blue Square vs Mammoth Mountain
Blue Square and Mammoth Mountain come from the same Behr collection. These are both blues, so the question isn't which hue to choose — it's where within blue to land. The 8-point LRV gap — 20 for Blue Square vs 11 for Mammoth Mountain — means Blue Square will open up a space more effectively. Both share a blue character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 12.5 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Blue Square vs Mammoth Mountain in Real Spaces
6 real rooms side by side. Seeing Blue Square and Mammoth Mountain 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Blue Square reflects noticeably more light off the walls, making the space read more open than Mammoth Mountain.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Blue Square returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Blue Square returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Blue Square returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. Blue Square returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Blue Square returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

5 simulated room previews — drag the slider on each to see Blue Square on one side and Mammoth Mountain on the other.
Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
