Royal Flax vs S 2005-Y40R
Where Royal Flax belongs to Benjamin Moore's range, S 2005-Y40R is a NCS color. These are both beige-greiges, so the question isn't which hue to choose — it's where within beige-greige to land. They have nearly identical light reflectance values (53 vs 53), so they'll read as similarly Medium in most lighting conditions. Royal Flax runs red while S 2005-Y40R is decidedly warm, which means they'll respond very differently to warm vs cool light sources. At ΔE 1.4, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room.
