Blue Opal vs Agapanthus
Where Blue Opal belongs to PPG's range, Agapanthus is a Sherwin-Williams color. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. They have nearly identical light reflectance values (56 vs 56), so they'll read as similarly Light in most lighting conditions. The ΔE 3.3 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
