Greens vs Poseidon
Greens and Poseidon come from the same Sherwin-Williams collection. Greens reads as green, while Poseidon reads as blue — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 10 vs 11 — so neither will read significantly brighter or darker than the other. Both share a cool character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 14.8 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Greens vs Poseidon in Real Spaces
2 real rooms side by side. Seeing Greens and Poseidon in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

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