Agate Grey vs Flannel
Where Agate Grey belongs to RAL Classic's range, Flannel is a Tikkurila color. These are both green-greys, so the question isn't which hue to choose — it's where within green-grey to land. Flannel (LRV 51) reflects noticeably more light than Agate Grey (LRV 45), a difference of 6 points that becomes especially apparent in rooms with limited natural light. The ΔE 6.3 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
