SeaglassBehrvsTranquil DawnDuluxΔE 12.8Distinct difference

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. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
