Goblin vs Poseidon
Where Goblin belongs to Little Greene's range, Poseidon is a Sherwin-Williams color. These are both blues, so the question isn't which hue to choose — it's where within blue to land. They have nearly identical light reflectance values (11 vs 11), so they'll read as similarly Dark in most lighting conditions. Goblin runs blue while Poseidon is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 17.3, 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.

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.
