Regatta vs Royal
Where Regatta belongs to Sherwin-Williams's range, Royal is a Tikkurila color. These are both blues, so the question isn't which hue to choose — it's where within blue to land. They have nearly identical light reflectance values (8 vs 9), so they'll read as similarly Dark in most lighting conditions. The ΔE 8.4 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
