Timeless vs RAL 150-4
Timeless (Dulux) and RAL 150-4 (RAL Effect) come from different manufacturers. Timeless reads as beige-yellow, while RAL 150-4 reads as beige — two distinct hue families, not close cousins. The 6-point LRV gap — 87 for Timeless vs 81 for RAL 150-4 — means Timeless will open up a space more effectively. ΔE 8.7 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Timeless vs RAL 150-4 in Real Spaces
5 real rooms side by side. Timeless and RAL 150-4 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. Timeless 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. Timeless has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Timeless 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. Timeless has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Timeless has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Timeless vs RAL 150-4 Simulated Comparison
5 simulated room previews — drag the slider on each to see Timeless on one side and RAL 150-4 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.
