Frosted Steel vs Thimble Case
Both from Dulux's palette. Frosted Steel reads as blue-grey, while Thimble Case reads as greige-grey — two distinct hue families, not close cousins. Frosted Steel (LRV 72) reflects noticeably more light than Thimble Case (LRV 68), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Frosted Steel runs cool while Thimble Case is decidedly warm, which means they'll respond very differently to warm vs cool light sources. 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 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Frosted Steel vs Thimble Case in Real Spaces
2 real rooms side by side. Frosted Steel and Thimble Case 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 — Frosted Steel 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. Frosted Steel 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.
