RAL 720-1 vs RAL 730-1
RAL 720-1 and RAL 730-1 come from the same RAL Effect collection. These are both blues, so the question isn't which hue to choose — it's where within blue to land. The 4-point LRV gap — 73 for RAL 730-1 vs 69 for RAL 720-1 — means RAL 730-1 will open up a space more effectively. A ΔE of 2.4 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
RAL 720-1 vs RAL 730-1 in Real Spaces
1 real room side by side. RAL 720-1 and RAL 730-1 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. RAL 730-1 reads slightly lighter here — a subtle but real difference in how open the space feels.

5 simulated room previews — drag the slider on each to see RAL 720-1 on one side and RAL 730-1 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.
