Prussian Blue vs Thunder
Both from Benjamin Moore's palette. Prussian Blue reads as blue, while Thunder reads as greige-grey — two distinct hue families, not close cousins. Thunder (LRV 48) reflects noticeably more light than Prussian Blue (LRV 12), a difference of 35 points that becomes especially apparent in rooms with limited natural light. Prussian Blue runs blue while Thunder is decidedly red, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 48.6, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.

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 Thunder will make the room feel meaningfully brighter than Prussian Blue would.

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.
