Whirlybird vs Seawashed Glass
Where Whirlybird belongs to Farrow & Ball's range, Seawashed Glass is a Sherwin-Williams color. These are both greens, so the question isn't which hue to choose — it's where within green to land. They have nearly identical light reflectance values (46 vs 48), so they'll read as similarly Medium in most lighting conditions. Both lean neutral, so they'll behave similarly in mixed or changing light conditions. The ΔE 9.5 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
