Caldwell Green vs Millstream
Caldwell Green (Benjamin Moore) and Millstream (Behr) come from different manufacturers. Caldwell Green reads as green-grey, while Millstream reads as blue — two distinct hue families, not close cousins. The 45-point LRV gap — 61 for Millstream vs 16 for Caldwell Green — means Millstream will open up a space more effectively. Where Caldwell Green leans green, Millstream reads blue — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 39.0 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Caldwell Green vs Millstream in Real Spaces
4 real rooms side by side. Seeing Caldwell Green 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 Caldwell Green.

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.

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.

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.

Caldwell Green vs Millstream Simulated Comparison
5 simulated room previews — drag the slider on each to see Caldwell Green 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.
