Castlegate vs High Sierra
Both are Sherwin-Williams colors. Castlegate reads as grey, while High Sierra reads as beige-greige — two distinct hue families, not close cousins. At LRV 53 vs 37, High Sierra will read as the brighter of the two — a 16-point gap that matters most in north-facing or low-light rooms. The tonal difference — Castlegate's neutral character against High Sierra's warm — becomes most visible against white trim or in morning light. At ΔE 13.6, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions. Below you'll find 10 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Castlegate vs High Sierra in Real Spaces
10 real rooms side by side. Seeing Castlegate and High Sierra 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
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. High Sierra returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The LRV gap is large enough that High Sierra will make the room feel meaningfully brighter than Castlegate would.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The LRV gap is large enough that High Sierra will make the room feel meaningfully brighter than Castlegate would.
Dining Room
Dining room light is typically the warmest in the house, which shifts both colors toward the red end of the spectrum compared to daylight. High Sierra reflects noticeably more light off the walls, making the space read more open than Castlegate.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that High Sierra will make the room feel meaningfully brighter than Castlegate would.
Home Office
In a home office, wall color sits in your peripheral vision for hours at a time, so temperature and undertone matter more than you might expect. The LRV gap is large enough that High Sierra will make the room feel meaningfully brighter than Castlegate would.
Mudroom
A mudroom color needs to hold up under the most casual scrutiny: a glance as you're coming and going, often in mixed or artificial light. High Sierra reflects noticeably more light off the walls, making the space read more open than Castlegate.
Patio
Patio colors are seen under changing outdoor light throughout the day — morning, midday, and golden hour each reveal different qualities. High Sierra reflects noticeably more light off the walls, making the space read more open than Castlegate.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The LRV gap is large enough that High Sierra will make the room feel meaningfully brighter than Castlegate would.
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. High Sierra returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

5 simulated room previews — drag the slider on each to see Castlegate on one side and High Sierra on the other.
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.
