Hematite vs RAL 820-4
Hematite is a Cloverdale Paint color while RAL 820-4 comes from RAL Effect. Hematite reads as grey, while RAL 820-4 reads as blue-grey — two distinct hue families, not close cousins. With LRVs of 24 and 23, they'll behave almost identically in terms of how much light they reflect back into a room. With a ΔE of 1.2, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Hematite vs RAL 820-4 in Real Spaces
3 real rooms side by side. Hematite and RAL 820-4 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.
Living Room
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.

Hematite vs RAL 820-4 Simulated Comparison
5 simulated room previews — drag the slider on each to see Hematite on one side and RAL 820-4 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.
