Placid Sea vs Aquarium
Placid Sea (Behr) and Aquarium (Sherwin-Williams) come from different manufacturers. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. The 10-point LRV gap — 32 for Aquarium vs 23 for Placid Sea — means Aquarium will open up a space more effectively. Where Placid Sea leans blue, Aquarium reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 5.4 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Placid Sea vs Aquarium in Real Spaces
3 real rooms side by side. Placid Sea and Aquarium 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. Aquarium reflects noticeably more light off the walls, making the space read more open than Placid Sea.
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. Aquarium 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. Aquarium reflects noticeably more light off the walls, making the space read more open than Placid Sea.

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.
