Dark Night vs Deep Sea Dive
Both from Sherwin-Williams's palette. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Deep Sea Dive (LRV 10) reflects noticeably more light than Dark Night (LRV 4), a difference of 7 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 17.7, 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.
Dark Night vs Deep Sea Dive in Real Spaces
6 real rooms side by side. Seeing Dark Night and Deep Sea Dive 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 brightness difference is modest but present — Deep Sea Dive gives the walls a little more lift.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Deep Sea Dive reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Deep Sea Dive reads slightly lighter here — a subtle but real difference in how open the space feels.
Home Office
The test for a home office color isn't how it looks in a quick glance — it's whether it still feels right after a full day of work. Deep Sea Dive reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Deep Sea Dive reads slightly lighter here — a subtle but real difference in how open the space feels.
Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. The brightness difference is modest but present — Deep Sea Dive gives the walls a little more lift.

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.
