Grey white vs Dewy
Grey white (RAL Classic) and Dewy (Sherwin-Williams) come from different manufacturers. Grey white reads as greige-grey, while Dewy reads as green — two distinct hue families, not close cousins. The 6-point LRV gap — 73 for Dewy vs 67 for Grey white — means Dewy will open up a space more effectively. ΔE 5.5 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Grey white vs Dewy in Real Spaces
1 real room side by side. Grey white and Dewy 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.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. Dewy has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Grey white vs Dewy Simulated Comparison
5 simulated room previews — drag the slider on each to see Grey white on one side and Dewy 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.
