Neptune Seas vs Mediterranean
Neptune Seas is a Dulux color while Mediterranean comes from Sherwin-Williams. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. With LRVs of 19 and 18, they'll behave almost identically in terms of how much light they reflect back into a room. They share a cool quality — useful to know if you're layering them in the same space. At ΔE 3.8, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Neptune Seas vs Mediterranean in Real Spaces
1 real room side by side. Neptune Seas and Mediterranean 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
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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

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.
