Fresh Eucalyptus vs Halcyon Green
Both from Sherwin-Williams's palette. These are both green-greys, so the question isn't which hue to choose — it's where within green-grey to land. Fresh Eucalyptus (LRV 48) reflects noticeably more light than Halcyon Green (LRV 38), a difference of 10 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 6.7 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Fresh Eucalyptus vs Halcyon Green in Real Spaces
1 real room side by side. Fresh Eucalyptus and Halcyon Green 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 LRV gap is large enough that Fresh Eucalyptus will make the room feel meaningfully brighter than Halcyon Green would.

5 simulated room previews — drag the slider on each to see Fresh Eucalyptus on one side and Halcyon Green 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.
