Dix Blue vs RAL 670-2
Dix Blue (Farrow & Ball) and RAL 670-2 (RAL Effect) come from different manufacturers. Dix Blue reads as blue-grey, while RAL 670-2 reads as blue — two distinct hue families, not close cousins. The 17-point LRV gap — 58 for RAL 670-2 vs 41 for Dix Blue — means RAL 670-2 will open up a space more effectively. A ΔE of 22.6 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.
Dix Blue vs RAL 670-2 in Real Spaces
5 real rooms side by side. Seeing Dix Blue and RAL 670-2 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. RAL 670-2 reflects noticeably more light off the walls, making the space read more open than Dix Blue.
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. RAL 670-2 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. RAL 670-2 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. RAL 670-2 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. RAL 670-2 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Dix Blue vs RAL 670-2 Simulated Comparison
5 simulated room previews — drag the slider on each to see Dix Blue on one side and RAL 670-2 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.
