Ecru vs Underseas
Both from Sherwin-Williams's palette. Hue-wise, Ecru belongs to the beige family and Underseas to the green-grey family. Ecru (LRV 51) reflects noticeably more light than Underseas (LRV 25), a difference of 25 points that becomes especially apparent in rooms with limited natural light. Ecru runs warm while Underseas is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 29.8, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Ecru vs Underseas in Real Spaces
6 real rooms side by side. Seeing Ecru and Underseas 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The LRV gap is large enough that Ecru will make the room feel meaningfully brighter than Underseas would.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Ecru reflects noticeably more light off the walls, making the space read more open than Underseas.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Ecru reflects noticeably more light off the walls, making the space read more open than Underseas.
Mudroom
Mudrooms are seen in passing, often under whatever light comes through the door — a context that favors colors with some depth. Ecru returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. Ecru reflects noticeably more light off the walls, making the space read more open than Underseas.

Ecru vs Underseas Simulated Comparison
5 simulated room previews — drag the slider on each to see Ecru on one side and Underseas 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.
