Undertone: Saturated blue-green (a color, not a neutral)
In CIELAB, Poseidon sits at L* 61.5, a* -36.4, b* -7.7. Its hue angle is 192° and its chroma is 37.2, so it reads as an outright blue-green rather than a neutral. It classifies as cool. Among Benjamin Moore colors with a similar LRV (±5), it is warmer (more yellow) than 15%.
LRV 31.4: mid-tone
Light Reflectance Value runs from 0 (absolute black) to 100 (perfect white). At 31.4, Poseidon is lighter than 34% of Benjamin Moore colors. Reads clearly as a color. Best in rooms with good natural light, or as an accent wall; small dark rooms may feel smaller.
