Hamilton Blue vs RAL 180-1
Hamilton Blue (Benjamin Moore) and RAL 180-1 (RAL Effect) come from different manufacturers. Hamilton Blue reads as blue-grey, while RAL 180-1 reads as blue — two distinct hue families, not close cousins. The 30-point LRV gap — 49 for RAL 180-1 vs 18 for Hamilton Blue — means RAL 180-1 will open up a space more effectively. A ΔE of 27.5 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Hamilton Blue vs RAL 180-1 in Real Spaces
3 real rooms side by side. Seeing Hamilton Blue and RAL 180-1 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 180-1 reflects noticeably more light off the walls, making the space read more open than Hamilton Blue.
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 180-1 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 180-1 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Hamilton Blue vs RAL 180-1 Simulated Comparison
5 simulated room previews — drag the slider on each to see Hamilton Blue on one side and RAL 180-1 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.
