Jet black vs Grey Blue
Jet black and Grey Blue come from the same RAL Classic collection. The 3-point LRV gap — 7 for Grey Blue vs 4 for Jet black — means Grey Blue will open up a space more effectively. A ΔE of 28.7 puts these firmly in different territory — two distinct design choices rather than close alternatives.
Jet black vs Grey Blue Color Comparison
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.

Jet black vs Grey Blue in Real Spaces
Seeing Jet black and Grey Blue in actual rooms makes the difference concrete. Browse the spaces below to get a feel for how each color lives on a wall. Showing 3 room types where both colors have photos.
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. Grey Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. Grey Blue reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Grey Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
