RAL 570-3 vs RAL 570-4
Both from RAL Effect's palette. These are both blues, so the question isn't which hue to choose — it's where within blue to land. RAL 570-3 (LRV 45) reflects noticeably more light than RAL 570-4 (LRV 35), a difference of 9 points that becomes especially apparent in rooms with limited natural light. The ΔE 7.6 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
RAL 570-3 vs RAL 570-4 in Real Spaces
4 real rooms side by side. RAL 570-3 and RAL 570-4 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The LRV gap is large enough that RAL 570-3 will make the room feel meaningfully brighter than RAL 570-4 would.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. RAL 570-3 reflects noticeably more light off the walls, making the space read more open than RAL 570-4.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. RAL 570-3 reflects noticeably more light off the walls, making the space read more open than RAL 570-4.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. RAL 570-3 reflects noticeably more light off the walls, making the space read more open than RAL 570-4.

5 simulated room previews — drag the slider on each to see RAL 570-3 on one side and RAL 570-4 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.
