Eventide vs Halcyon Green
Both from Sherwin-Williams's palette. Eventide reads as blue-green, while Halcyon Green reads as green-grey — two distinct hue families, not close cousins. Eventide (LRV 41) reflects noticeably more light than Halcyon Green (LRV 38), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Eventide runs neutral while Halcyon Green is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 3.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Eventide vs Halcyon Green in Real Spaces
4 real rooms side by side. Eventide 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 brightness difference is modest but present — Eventide gives the walls a little more lift.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Eventide reads slightly lighter here — a subtle but real difference in how open the space feels.
Dining Room
A dining room lit by a dimmed pendant or candles is one of the most forgiving environments for paint — warm light softens almost everything. Eventide has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Eventide 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.
