High Sierra vs Mushroom
High Sierra and Mushroom come from the same Sherwin-Williams collection. These are both beige-greiges, so the question isn't which hue to choose — it's where within beige-greige to land. The 4-point LRV gap — 57 for Mushroom vs 53 for High Sierra — means Mushroom will open up a space more effectively. Both share a warm character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 3.0 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
High Sierra vs Mushroom in Real Spaces
1 real room side by side. High Sierra and Mushroom 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. Mushroom reads slightly lighter here — a subtle but real difference in how open the space feels.

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.
