Celtic Blue vs Cystern
Celtic Blue (Benjamin Moore) and Cystern (Cloverdale Paint) come from different manufacturers. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. The 45-point LRV gap — 45 for Cystern vs 0 for Celtic Blue — means Cystern will open up a space more effectively. A ΔE of 2.4 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Digital color is approximate.
