Extreme Yellow vs RAL 270-4
Where Extreme Yellow belongs to Behr's range, RAL 270-4 is a RAL Effect color. These are both beige-yellows, so the question isn't which hue to choose — it's where within beige-yellow to land. Extreme Yellow (LRV 50) reflects noticeably more light than RAL 270-4 (LRV 43), a difference of 8 points that becomes especially apparent in rooms with limited natural light. The ΔE 7.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
