Undersea vs Denim Drift
Undersea is a Behr color while Denim Drift comes from Dulux. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. At LRV 27 vs 9, Denim Drift will read as the brighter of the two — a 18-point gap that matters most in north-facing or low-light rooms. The tonal difference — Undersea's blue character against Denim Drift's cool — becomes most visible against white trim or in morning light. At ΔE 21.1, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions.

2 real rooms side by side. Seeing Undersea and Denim Drift 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. Denim Drift 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 Denim Drift will make the room feel meaningfully brighter than Undersea would.
