Mountain Dew vs Signal White
Where Mountain Dew belongs to PPG's range, Signal White is a RAL Classic color. Mountain Dew reads as blue, while Signal White reads as white — two distinct hue families, not close cousins. Signal White (LRV 85) reflects noticeably more light than Mountain Dew (LRV 77), a difference of 8 points that becomes especially apparent in rooms with limited natural light. The ΔE 8.7 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
