Mountain Forest vs Grass green
Where Mountain Forest belongs to PPG's range, Grass green is a RAL Classic color. Both sit in the green family, which is useful context if you're narrowing within a single hue direction. Grass green (LRV 15) reflects noticeably more light than Mountain Forest (LRV 11), a difference of 4 points that becomes especially apparent in rooms with limited natural light. The ΔE 8.9 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
