Vast Lake vs RAL 610-1
Vast Lake (Dulux) and RAL 610-1 (RAL Effect) come from different manufacturers. These are both blues, so the question isn't which hue to choose — it's where within blue to land. The 6-point LRV gap — 31 for Vast Lake vs 25 for RAL 610-1 — means Vast Lake will open up a space more effectively. ΔE 7.2 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.
Vast Lake vs RAL 610-1 in Real Spaces
2 real rooms side by side. Vast Lake and RAL 610-1 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. Vast Lake 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. Vast Lake has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Vast Lake vs RAL 610-1 Simulated Comparison
5 simulated room previews — drag the slider on each to see Vast Lake on one side and RAL 610-1 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.
