Blue Echo vs Millstream
Blue Echo and Millstream come from the same Behr collection. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. The 18-point LRV gap — 61 for Millstream vs 43 for Blue Echo — means Millstream will open up a space more effectively. Both share a blue character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 12.0 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Blue Echo vs Millstream in Real Spaces
6 real rooms side by side. Seeing Blue Echo and Millstream 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
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. Millstream reflects noticeably more light off the walls, making the space read more open than Blue Echo.
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. Millstream returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Millstream returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Millstream returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Millstream returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Millstream returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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