Cobalt Embrace vs RAL 640-6
Cobalt Embrace (Dulux) and RAL 640-6 (RAL Effect) come from different manufacturers. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. The 4-point LRV gap — 9 for Cobalt Embrace vs 5 for RAL 640-6 — means Cobalt Embrace will open up a space more effectively. ΔE 3.3 means they're clearly different, but not dramatically so — they'd pair well in the same room.

Cobalt Embrace vs RAL 640-6 in Real Spaces
2 real rooms side by side. Cobalt Embrace and RAL 640-6 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. Cobalt Embrace 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. Cobalt Embrace has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

5 simulated room previews — drag the slider on each to see Cobalt Embrace on one side and RAL 640-6 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.
