Millstream vs RAL 180-2
Millstream 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 61 vs 58, Millstream will read as the brighter of the two — a 3-point gap that matters most in north-facing or low-light rooms. At ΔE 4.5, 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.
Millstream vs RAL 180-2 in Real Spaces
5 real rooms side by side. Millstream 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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
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.
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.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small 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 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.

Millstream vs RAL 180-2 Simulated Comparison
5 simulated room previews — drag the slider on each to see Millstream 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.
