Sun Dust 2 vs RAL 370-1
Sun Dust 2 (Dulux) and RAL 370-1 (RAL Effect) come from different manufacturers. Both sit in the beige family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 49 vs 49 — so neither will read significantly brighter or darker than the other. A ΔE of 11.8 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Sun Dust 2 vs RAL 370-1 in Real Spaces
3 real rooms side by side. Seeing Sun Dust 2 and RAL 370-1 in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. The distinction reads clearly at room scale, making the choice between them concrete.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

Sun Dust 2 vs RAL 370-1 Simulated Comparison
5 simulated room previews — drag the slider on each to see Sun Dust 2 on one side and RAL 370-1 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.
