RAL 820-1 vs Tradewind
Where RAL 820-1 belongs to RAL Effect's range, Tradewind is a Sherwin-Williams color. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. Tradewind (LRV 61) reflects noticeably more light than RAL 820-1 (LRV 57), a difference of 3 points that becomes especially apparent in rooms with limited natural light. The ΔE 4.1 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

RAL 820-1 vs Tradewind in Real Spaces
4 real rooms side by side. RAL 820-1 and Tradewind 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The brightness difference is modest but present — Tradewind gives the walls a little more lift.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Tradewind reads slightly lighter here — a subtle but real difference in how open the space feels.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Tradewind reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Tradewind reads slightly lighter here — a subtle but real difference in how open the space feels.

RAL 820-1 vs Tradewind Simulated Comparison
5 simulated room previews — drag the slider on each to see RAL 820-1 on one side and Tradewind 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.
