At LRV 35 vs 33, RAL 720-4 will read as the brighter of the two — a 3-point gap that matters most in north-facing or low-light rooms. At ΔE 6.0, 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 690-1 vs RAL 720-4 in Real Spaces
3 real rooms side by side. RAL 690-1 and RAL 720-4 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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
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.
Kitchen Cabinets
On cabinetry, undertone and temperature become more pronounced against countertops and hardware. 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 690-1 vs RAL 720-4 Simulated Comparison
5 simulated room previews — drag the slider on each to see RAL 690-1 on one side and RAL 720-4 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.
