Lagoon vs Pure White
Both are Sherwin-Williams colors. Lagoon reads as blue, while Pure White reads as beige-greige — two distinct hue families, not close cousins. At LRV 84 vs 20, Pure White will read as the brighter of the two — a 64-point gap that matters most in north-facing or low-light rooms. The tonal difference — Lagoon's cool character against Pure White's warm — becomes most visible against white trim or in morning light. At ΔE 45.2, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Lagoon vs Pure White in Real Spaces
2 real rooms side by side. Seeing Lagoon and Pure White in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Front Door
Front doors are seen in isolation against the rest of the facade, which makes them a high-stakes surface where even subtle differences matter. Pure White returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen Cabinets
On cabinetry, undertone and temperature become more pronounced against countertops and hardware. The LRV gap is large enough that Pure White will make the room feel meaningfully brighter than Lagoon would.

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.
