Yellow grey vs RAL 770-M
Yellow grey (RAL Classic) and RAL 770-M (RAL Effect) come from different manufacturers. Yellow grey reads as greige-grey, while RAL 770-M reads as beige-greige — two distinct hue families, not close cousins. The 3-point LRV gap — 27 for Yellow grey vs 24 for RAL 770-M — means Yellow grey will open up a space more effectively. ΔE 6.4 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Yellow grey vs RAL 770-M in Real Spaces
2 real rooms side by side. Yellow grey and RAL 770-M 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. Yellow grey reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Yellow grey has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Yellow grey vs RAL 770-M Simulated Comparison
5 simulated room previews — drag the slider on each to see Yellow grey on one side and RAL 770-M 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.
