Blue Granite vs RAL 180-M
Blue Granite (Cloverdale Paint) and RAL 180-M (RAL Effect) come from different manufacturers. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. The 4-point LRV gap — 39 for Blue Granite vs 35 for RAL 180-M — means Blue Granite will open up a space more effectively. A ΔE of 2.7 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Blue Granite vs RAL 180-M in Real Spaces
3 real rooms side by side. Blue Granite and RAL 180-M 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.
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. Blue Granite reads slightly lighter here — a subtle but real difference in how open the space feels.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Blue Granite has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Blue Granite has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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