Key Largo vs Light green
Where Key Largo belongs to PPG's range, Light green is a RAL Classic color. These are both blue-greens, so the question isn't which hue to choose — it's where within blue-green to land. Light green (LRV 44) reflects noticeably more light than Key Largo (LRV 40), a difference of 4 points that becomes especially apparent in rooms with limited natural light. The ΔE 7.4 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
