RAL 150-4 vs Gentle Lamb
RAL 150-4 (RAL Effect) and Gentle Lamb (Valspar) come from different manufacturers. These are both beiges, so the question isn't which hue to choose — it's where within beige to land. The 11-point LRV gap — 81 for RAL 150-4 vs 70 for Gentle Lamb — means RAL 150-4 will open up a space more effectively. ΔE 6.9 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.
RAL 150-4 vs Gentle Lamb in Real Spaces
2 real rooms side by side. RAL 150-4 and Gentle Lamb 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. RAL 150-4 reflects noticeably more light off the walls, making the space read more open than Gentle Lamb.
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. RAL 150-4 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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.
