Green Sponge vs Synergy
Where Green Sponge belongs to Benjamin Moore's range, Synergy is a Sherwin-Williams color. Green Sponge reads as blue-green, while Synergy reads as blue — two distinct hue families, not close cousins. They have nearly identical light reflectance values (44 vs 43), so they'll read as similarly Medium in most lighting conditions. Green Sponge runs green and blue while Synergy is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 5.5 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

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.
