Andiron vs Thunderous in Real Spaces
3 real rooms side by side. Seeing Andiron and Thunderous in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Living Room
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Thunderous returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The LRV gap is large enough that Thunderous will make the room feel meaningfully brighter than Andiron would.
Home Office
In a home office, wall color sits in your peripheral vision for hours at a time, so temperature and undertone matter more than you might expect. The LRV gap is large enough that Thunderous will make the room feel meaningfully brighter than Andiron 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.
