Gentian vs Lupine
Gentian and Lupine 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. Their light reflectance values are nearly the same — 18 vs 16 — so neither will read significantly brighter or darker than the other. Both share a cool character, which means they'll respond to light and surrounding materials in similar ways. ΔE 8.7 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.

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.
