Iced Slate vs RAL 170-1
Iced Slate (Benjamin Moore) and RAL 170-1 (RAL Effect) come from different manufacturers. Iced Slate reads as blue, while RAL 170-1 reads as blue-grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 58 vs 58 — so neither will read significantly brighter or darker than the other. A ΔE of 2.5 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Iced Slate vs RAL 170-1 in Real Spaces
1 real room side by side. Iced Slate and RAL 170-1 are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
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. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

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.
