Opal Waters vs RAL 180-2
Opal Waters is a Behr color while RAL 180-2 comes from RAL Effect. These are both blues, so the question isn't which hue to choose — it's where within blue to land. At LRV 58 vs 53, RAL 180-2 will read as the brighter of the two — a 5-point gap that matters most in north-facing or low-light rooms. At ΔE 3.8, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Opal Waters vs RAL 180-2 in Real Spaces
5 real rooms side by side. Opal Waters and RAL 180-2 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. RAL 180-2 has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The brightness difference is modest but present — RAL 180-2 gives the walls a little more lift.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The brightness difference is modest but present — RAL 180-2 gives the walls a little more lift.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The brightness difference is modest but present — RAL 180-2 gives the walls a little more lift.
Kitchen Cabinets
On cabinetry, undertone and temperature become more pronounced against countertops and hardware. The brightness difference is modest but present — RAL 180-2 gives the walls a little more lift.

5 simulated room previews — drag the slider on each to see Opal Waters on one side and RAL 180-2 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.
