Jet Black vs RAL 790-4
Where Jet Black belongs to Benjamin Moore's range, RAL 790-4 is a RAL Effect color. These are both greys, so the question isn't which hue to choose — it's where within grey to land. They have nearly identical light reflectance values (5 vs 4), so they'll read as similarly Dark in most lighting conditions. At ΔE 2.2, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Jet Black vs RAL 790-4 in Real Spaces
2 real rooms side by side. Jet Black and RAL 790-4 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.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

Jet Black vs RAL 790-4 Simulated Comparison
5 simulated room previews — drag the slider on each to see Jet Black on one side and RAL 790-4 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.
