Undine vs Hazy Blue
Where Undine belongs to Behr's range, Hazy Blue is a Benjamin Moore color. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. Hazy Blue (LRV 50) reflects noticeably more light than Undine (LRV 43), a difference of 7 points that becomes especially apparent in rooms with limited natural light. Both lean green and blue, so they'll behave similarly in mixed or changing light conditions. The ΔE 3.1 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

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.
