Frosted Lilac vs RAL 170-1
Where Frosted Lilac belongs to PPG's range, RAL 170-1 is a RAL Effect color. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Frosted Lilac (LRV 65) reflects noticeably more light than RAL 170-1 (LRV 58), a difference of 7 points that becomes especially apparent in rooms with limited natural light. The ΔE 4.2 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
