Undertone: Subtle yellow undertone
In CIELAB, Grey Heron sits at L* 84.3, a* 0.0, b* 4.4. Its hue angle is 90° and its chroma is 4.4, so it leans yellow only slightly — the undertone mostly shows next to whiter or grayer colors. It classifies as warm. Among Sherwin-Williams colors with a similar LRV (±5), it is warmer (more yellow) than 38%.
LRV 64.8: light
