RAL 180-1 vs RAL 720-4
Both are RAL Effect colors. These are both blues, so the question isn't which hue to choose — it's where within blue to land. At LRV 49 vs 35, RAL 180-1 will read as the brighter of the two — a 13-point gap that matters most in north-facing or low-light rooms. At ΔE 26.4, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
RAL 180-1 vs RAL 720-4 in Real Spaces
3 real rooms side by side. Seeing RAL 180-1 and RAL 720-4 in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. RAL 180-1 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that RAL 180-1 will make the room feel meaningfully brighter than RAL 720-4 would.

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.
