O'Reilly Green vs Acorn
O'Reilly Green (Benjamin Moore) and Acorn (Little Greene) come from different manufacturers. O'Reilly Green reads as green, while Acorn reads as yellow — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 74 vs 75 — so neither will read significantly brighter or darker than the other. Where O'Reilly Green leans neutral, Acorn reads yellow — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 13.6 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
