Portsmouth vs Taiga

Both from Sherwin-Williams's palette. Portsmouth reads as blue-grey, while Taiga reads as grey — two distinct hue families, not close cousins. They have nearly identical light reflectance values (22 vs 21), 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 4.0 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
