Platinum grey vs Coquina
Where Platinum grey belongs to RAL Classic's range, Coquina is a Sherwin-Williams color. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. Platinum grey (LRV 32) reflects noticeably more light than Coquina (LRV 28), a difference of 4 points that becomes especially apparent in rooms with limited natural light. The ΔE 5.1 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
