Cook's Blue vs Cobalt Stone
Cook's Blue (Farrow & Ball) and Cobalt Stone (PPG) come from different manufacturers. These are both blues, so the question isn't which hue to choose — it's where within blue to land. The 11-point LRV gap — 25 for Cook's Blue vs 14 for Cobalt Stone — means Cook's Blue will open up a space more effectively. A ΔE of 29.8 puts these firmly in different territory — two distinct design choices rather than close alternatives.
