Impromptu vs Jay Blue
Both from Sherwin-Williams's palette. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. Impromptu (LRV 23) reflects noticeably more light than Jay Blue (LRV 9), a difference of 14 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 22.4, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

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.
