Atmospheric vs Cay
Atmospheric and Cay come from the same Sherwin-Williams collection. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. The 9-point LRV gap — 67 for Atmospheric vs 58 for Cay — means Atmospheric will open up a space more effectively. Both share a cool character, which means they'll respond to light and surrounding materials in similar ways. ΔE 7.6 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 10 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Atmospheric vs Cay in Real Spaces
10 real rooms side by side. Atmospheric and Cay 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
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. Atmospheric reflects noticeably more light off the walls, making the space read more open than Cay.
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. Atmospheric 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. Atmospheric returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The LRV gap is large enough that Atmospheric will make the room feel meaningfully brighter than Cay would.
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. Atmospheric returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Home Office
Home office walls matter more than most — you're looking at them all day, and a color that reads fine at first can become tiring over time. Atmospheric returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Mudroom
In a hardworking space like a mudroom, the depth and warmth of a color reads differently than in a quieter room. The LRV gap is large enough that Atmospheric will make the room feel meaningfully brighter than Cay would.
Patio
Exterior colors look different in open light — both tend to read lighter outside than on an interior swatch, and shadows read more strongly. The LRV gap is large enough that Atmospheric will make the room feel meaningfully brighter than Cay would.
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. Atmospheric returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. Atmospheric reflects noticeably more light off the walls, making the space read more open than Cay.

Atmospheric vs Cay Simulated Comparison
5 simulated room previews — drag the slider on each to see Atmospheric on one side and Cay 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.
