Loch Blue vs Pure White
Loch Blue and Pure White come from the same Sherwin-Williams collection. Loch Blue reads as blue, while Pure White reads as beige-greige — two distinct hue families, not close cousins. The 68-point LRV gap — 84 for Pure White vs 16 for Loch Blue — means Pure White will open up a space more effectively. Where Loch Blue leans cool, Pure White reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 53.3 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Loch Blue vs Pure White in Real Spaces
2 real rooms side by side. Seeing Loch Blue 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.
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. Pure White 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. Pure White reflects noticeably more light off the walls, making the space read more open than Loch Blue.

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.
