Roycroft Bronze Green vs Thunderous
Both from Sherwin-Williams's palette. Roycroft Bronze Green reads as green-greige, while Thunderous reads as grey — two distinct hue families, not close cousins. Thunderous (LRV 15) reflects noticeably more light than Roycroft Bronze Green (LRV 9), a difference of 6 points that becomes especially apparent in rooms with limited natural light. Roycroft Bronze Green runs warm while Thunderous is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. The ΔE 9.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

Roycroft Bronze Green vs Thunderous in Real Spaces
7 real rooms side by side. Roycroft Bronze Green and Thunderous 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 — Thunderous 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. Thunderous reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Thunderous 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. Thunderous 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. Thunderous 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 — Thunderous 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. Thunderous reads slightly lighter here — a subtle but real difference in how open the space feels.
