Guesthouse vs RAL 780-4
Guesthouse is a Benjamin Moore color while RAL 780-4 comes from RAL Effect. These are both beiges, so the question isn't which hue to choose — it's where within beige to land. At LRV 47 vs 40, RAL 780-4 will read as the brighter of the two — a 7-point gap that matters most in north-facing or low-light rooms. At ΔE 4.0, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.
