Deep Indigo vs Poseidon
Both from Benjamin Moore's palette. Deep Indigo reads as grey, while Poseidon reads as blue — two distinct hue families, not close cousins. Poseidon (LRV 31) reflects noticeably more light than Deep Indigo (LRV 8), a difference of 23 points that becomes especially apparent in rooms with limited natural light. Deep Indigo runs purple while Poseidon is decidedly blue, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 48.9, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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.
