Kensington Blue vs RAL 580-5

Kensington BlueBenjamin MoorevsRAL 580-5RAL EffectΔE 6.1Noticeable difference

Kensington Blue (Benjamin Moore) and RAL 580-5 (RAL Effect) come from different manufacturers. 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 — 12 for Kensington Blue vs 8 for RAL 580-5 — means Kensington Blue will open up a space more effectively. ΔE 6.1 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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.
