Cook's Blue vs Pulsating Blue
Cook's Blue (Farrow & Ball) and Pulsating Blue (Sherwin-Williams) 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 15-point LRV gap — 25 for Cook's Blue vs 10 for Pulsating Blue — means Cook's Blue will open up a space more effectively. Both share a cool character, which means they'll respond to light and surrounding materials in similar ways.
