Halcyon Green vs Jasper Stone
Both from Sherwin-Williams's palette. Both sit in the green-grey family, which is useful context if you're narrowing within a single hue direction. Halcyon Green (LRV 38) reflects noticeably more light than Jasper Stone (LRV 32), a difference of 6 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 4.7 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Halcyon Green vs Jasper Stone in Real Spaces
6 real rooms side by side. Halcyon Green and Jasper Stone 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The brightness difference is modest but present — Halcyon Green gives the walls a little more lift.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Halcyon Green reads slightly lighter here — a subtle but real difference in how open the space feels.
Home Office
The test for a home office color isn't how it looks in a quick glance — it's whether it still feels right after a full day of work. Halcyon Green reads slightly lighter here — a subtle but real difference in how open the space feels.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. Halcyon Green reads slightly lighter here — a subtle but real difference in how open the space feels.
Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. The brightness difference is modest but present — Halcyon Green gives the walls a little more lift.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. Halcyon Green reads slightly lighter here — a subtle but real difference in how open the space feels.

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.
