Bancha vs RAL 640-4
Bancha (Farrow & Ball) and RAL 640-4 (RAL Effect) come from different manufacturers. Bancha reads as beige-greige, while RAL 640-4 reads as blue — two distinct hue families, not close cousins. The 7-point LRV gap — 13 for Bancha vs 7 for RAL 640-4 — means Bancha will open up a space more effectively. A ΔE of 52.9 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.
Bancha vs RAL 640-4 in Real Spaces
5 real rooms side by side. Seeing Bancha and RAL 640-4 in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. Bancha has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Bancha 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. Bancha 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. Bancha 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. Bancha has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Bancha vs RAL 640-4 Simulated Comparison
5 simulated room previews — drag the slider on each to see Bancha on one side and RAL 640-4 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.
