RAL 650-4 vs RAL 650-5
Both are RAL Effect colors. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. With LRVs of 6 and 8, they'll behave almost identically in terms of how much light they reflect back into a room. At ΔE 4.3, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
RAL 650-4 vs RAL 650-5 in Real Spaces
3 real rooms side by side. RAL 650-4 and RAL 650-5 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.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.

RAL 650-4 vs RAL 650-5 Simulated Comparison
5 simulated room previews — drag the slider on each to see RAL 650-4 on one side and RAL 650-5 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.
