Lulworth Blue vs RAL 610-4
Lulworth Blue (Farrow & Ball) and RAL 610-4 (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 5-point LRV gap — 45 for Lulworth Blue vs 40 for RAL 610-4 — means Lulworth Blue will open up a space more effectively. A ΔE of 12.1 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Lulworth Blue vs RAL 610-4 in Real Spaces
5 real rooms side by side. Seeing Lulworth Blue and RAL 610-4 in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. Lulworth Blue 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. Lulworth Blue 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. Lulworth Blue 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. Lulworth Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Lulworth Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Lulworth Blue vs RAL 610-4 Simulated Comparison
5 simulated room previews — drag the slider on each to see Lulworth Blue on one side and RAL 610-4 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.
