Undertone: No measurable undertone (true neutral)
In CIELAB, Autonomous sits at L* 80.1, a* -0.7, b* 0.9. Its hue angle is 129° and its chroma is 1.1, so it has essentially no color cast — a true neutral that will pick up the color of the light and surroundings. It classifies as neutral. Among Sherwin-Williams colors with a similar LRV (±5), it is warmer (more yellow) than 23%.
LRV 56.8: light
Light Reflectance Value runs from 0 (absolute black) to 100 (perfect white). At 56.8, Autonomous is lighter than 68% of Sherwin-Williams colors. The most forgiving range for whole-house walls. Keeps rooms bright without glare.
