Lobelia vs Perfect Periwinkle
Both from Sherwin-Williams's palette. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Lobelia (LRV 30) reflects noticeably more light than Perfect Periwinkle (LRV 23), a difference of 7 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 6.7 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

Before committing to either color, test physical samples in your own space under the light you actually live with.
