Sea Emerald vs Cathedral Glass
Sea Emerald is a Jotun color while Cathedral Glass comes from PPG. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. At LRV 29 vs 26, Cathedral Glass will read as the brighter of the two — a 3-point gap that matters most in north-facing or low-light rooms. At ΔE 4.2, the difference is perceptible but not dramatic — the two can work harmoniously in the same space.
