Impromptu vs Resonant Blue
Impromptu and Resonant Blue come from the same Sherwin-Williams collection. These are both blues, so the question isn't which hue to choose — it's where within blue to land. The 7-point LRV gap — 30 for Resonant Blue vs 23 for Impromptu — means Resonant 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. ΔE 6.5 means they're clearly different, but not dramatically so — they'd pair well in the same room.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
