Chiltern White vs Nonchalant White
Chiltern White (Dulux) and Nonchalant White (Sherwin-Williams) come from different manufacturers. Chiltern White reads as greige-grey, while Nonchalant White reads as beige-greige — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 73 vs 72 — so neither will read significantly brighter or darker than the other. Both share a warm character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 2.7 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Chiltern White vs Nonchalant White in Real Spaces
1 real room side by side. Chiltern White and Nonchalant White 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.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

5 simulated room previews — drag the slider on each to see Chiltern White on one side and Nonchalant White on the other.
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.
