Onyx vs Icy Blue
Onyx is a Benjamin Moore color while Icy Blue comes from Jotun. Hue-wise, Onyx belongs to the grey family and Icy Blue to the blue-grey family. At LRV 25 vs 5, Icy Blue will read as the brighter of the two — a 20-point gap that matters most in north-facing or low-light rooms. The tonal difference — Onyx's red character against Icy Blue's cool — becomes most visible against white trim or in morning light. At ΔE 36.5, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions.

Onyx vs Icy Blue in Real Spaces
4 real rooms side by side. Seeing Onyx and Icy Blue 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. Icy Blue 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 Icy Blue will make the room feel meaningfully brighter than Onyx would.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that Icy Blue will make the room feel meaningfully brighter than Onyx would.

5 simulated room previews — drag the slider on each to see Onyx on one side and Icy Blue on the other.
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.
