Aquastone vs Lark Green
Aquastone and Lark Green come from the same Sherwin-Williams collection. Hue-wise, Aquastone belongs to the blue family and Lark Green to the green family. The 3-point LRV gap — 49 for Aquastone vs 46 for Lark Green — means Aquastone 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 9.5 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.
Aquastone vs Lark Green in Real Spaces
10 real rooms side by side. Aquastone and Lark Green 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. Aquastone reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Aquastone has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Aquastone has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The brightness difference is modest but present — Aquastone gives the walls a little more lift.
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. Aquastone has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Aquastone has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Mudroom
In a hardworking space like a mudroom, the depth and warmth of a color reads differently than in a quieter room. The brightness difference is modest but present — Aquastone gives the walls a little more lift.
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 brightness difference is modest but present — Aquastone gives the walls a little more lift.
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. Aquastone has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Aquastone reads slightly lighter here — a subtle but real difference in how open the space feels.

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.
