Halcyon Green vs Sigh of Relief
Halcyon Green (Sherwin-Williams) and Sigh of Relief (Valspar) come from different manufacturers. Both sit in the green-grey family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 38 vs 40 — so neither will read significantly brighter or darker than the other. ΔE 3.0 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Halcyon Green vs Sigh of Relief in Real Spaces
4 real rooms side by side. Halcyon Green and Sigh of Relief 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. The distinction reads clearly at room scale, making the choice between them concrete.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
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.

5 simulated room previews — drag the slider on each to see Halcyon Green on one side and Sigh of Relief 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.
