Cotton White vs White Flour
Both from Sherwin-Williams's palette. Both sit in the beige-white family, which is useful context if you're narrowing within a single hue direction. They have nearly identical light reflectance values (87 vs 87), so they'll read as similarly Light in most lighting conditions. Both lean warm, so they'll behave similarly in mixed or changing light conditions. At ΔE 1.5, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Cotton White vs White Flour in Real Spaces
3 real rooms side by side. Cotton White and White Flour are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

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.
