Millstream vs Atmospheric
Millstream (Behr) and Atmospheric (Sherwin-Williams) come from different manufacturers. These are both blues, so the question isn't which hue to choose — it's where within blue to land. The 6-point LRV gap — 67 for Atmospheric vs 61 for Millstream — means Atmospheric will open up a space more effectively. Where Millstream leans blue, Atmospheric reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 3.2 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Millstream vs Atmospheric in Real Spaces
5 real rooms side by side. Millstream and Atmospheric 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Atmospheric reads slightly lighter here — a subtle but real difference in how open the space feels.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Atmospheric has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Atmospheric has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Atmospheric has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. Atmospheric has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Millstream vs Atmospheric Simulated Comparison
5 simulated room previews — drag the slider on each to see Millstream on one side and Atmospheric 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.
