Blue Ground vs RAL 730-3
Blue Ground (Farrow & Ball) and RAL 730-3 (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 11-point LRV gap — 49 for Blue Ground vs 39 for RAL 730-3 — means Blue Ground will open up a space more effectively. ΔE 9.5 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Blue Ground vs RAL 730-3 in Real Spaces
3 real rooms side by side. Blue Ground and RAL 730-3 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. Blue Ground reflects noticeably more light off the walls, making the space read more open than RAL 730-3.
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. Blue Ground returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Blue Ground returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Blue Ground vs RAL 730-3 Simulated Comparison
5 simulated room previews — drag the slider on each to see Blue Ground on one side and RAL 730-3 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.
