Zero Gravity vs RAL 820-1
Zero Gravity is a Behr color while RAL 820-1 comes from RAL Effect. Zero Gravity reads as grey, while RAL 820-1 reads as blue-grey — two distinct hue families, not close cousins. With LRVs of 57 and 57, they'll behave almost identically in terms of how much light they reflect back into a room. With a ΔE of 1.8, the difference is subtle — you'd need them side by side to reliably tell them apart. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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