Windmill Lane vs RAL 850-4 in Real Spaces
4 real rooms side by side. Windmill Lane and RAL 850-4 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. Windmill Lane reads slightly lighter here — a subtle but real difference in how open the space feels.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Windmill Lane has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Windmill Lane has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Windmill Lane has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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.
