Blue Oasis vs RAL 620-1
Where Blue Oasis belongs to PPG's range, RAL 620-1 is a RAL Effect color. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Blue Oasis (LRV 15) reflects noticeably more light than RAL 620-1 (LRV 11), a difference of 4 points that becomes especially apparent in rooms with limited natural light. The ΔE 3.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
