Frontier Brown vs Portabello
Where Frontier Brown belongs to Behr's range, Portabello is a Sherwin-Williams color. These are both beige-greiges, so the question isn't which hue to choose — it's where within beige-greige to land. Frontier Brown (LRV 24) reflects noticeably more light than Portabello (LRV 21), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Frontier Brown runs red while Portabello is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 6.0 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
