Indigo vs Cay
Indigo is a Benjamin Moore color while Cay comes from Sherwin-Williams. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. With LRVs of 57 and 58, they'll behave almost identically in terms of how much light they reflect back into a room. The tonal difference — Indigo's blue character against Cay's cool — becomes most visible against white trim or in morning light. With a ΔE of 1.7, the difference is subtle — you'd need them side by side to reliably tell them apart. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

5 simulated room previews — drag the slider on each to see Indigo on one side and Cay on the other.
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.
