Castlegate vs Pure White
Castlegate and Pure White come from the same Sherwin-Williams collection. Castlegate reads as grey, while Pure White reads as beige-greige — two distinct hue families, not close cousins. The 47-point LRV gap — 84 for Pure White vs 37 for Castlegate — means Pure White will open up a space more effectively. Where Castlegate leans neutral, Pure White reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 26.2 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 7 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Castlegate vs Pure White in Real Spaces
7 real rooms side by side. Seeing Castlegate 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.
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. Pure White reflects noticeably more light off the walls, making the space read more open than Castlegate.
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. 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
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Pure White returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Pure White 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. Pure White returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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 Castlegate.

Digital color is approximate.
