Seaglass is a Behr color while Tranquil Dawn comes from Dulux. Seaglass reads as green, while Tranquil Dawn reads as green-grey — two distinct hue families, not close cousins. At LRV 73 vs 55, Seaglass 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 — Seaglass's green character against Tranquil Dawn's neutral — becomes most visible against white trim or in morning light. At ΔE 12.8, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions.

Seaglass vs Tranquil Dawn in Real Spaces
5 real rooms side by side. Seeing Seaglass and Tranquil Dawn 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. Seaglass 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 Seaglass will make the room feel meaningfully brighter than Tranquil Dawn would.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The LRV gap is large enough that Seaglass will make the room feel meaningfully brighter than Tranquil Dawn 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 Seaglass will make the room feel meaningfully brighter than Tranquil Dawn would.
Kitchen Cabinets
On cabinetry, undertone and temperature become more pronounced against countertops and hardware. The LRV gap is large enough that Seaglass will make the room feel meaningfully brighter than Tranquil Dawn would.

5 simulated room previews — drag the slider on each to see Seaglass on one side and Tranquil Dawn 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.
