Mushroom vs River Reed
Both from Sherwin-Williams's palette. These are both beige-greiges, so the question isn't which hue to choose — it's where within beige-greige to land. Mushroom (LRV 57) reflects noticeably more light than River Reed (LRV 25), a difference of 33 points that becomes especially apparent in rooms with limited natural light. Both lean warm, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 24.5, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Mushroom vs River Reed Simulated Comparison
5 simulated room previews — drag the slider on each to see Mushroom on one side and River Reed 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.

With LRVs of 60 and 57, the two reflect almost the same amount of light.
Their light reflectance is nearly identical (LRV 58 vs 57), so neither reads brighter in a room.
