Blue Note vs Dock Blue

Blue NoteBenjamin MoorevsDock BlueLittle GreeneΔE 8.8Noticeable difference

Where Blue Note belongs to Benjamin Moore's range, Dock Blue is a Little Greene color. Blue Note reads as blue-grey, while Dock Blue reads as blue — two distinct hue families, not close cousins. Blue Note (LRV 9) reflects noticeably more light than Dock Blue (LRV 4), a difference of 5 points that becomes especially apparent in rooms with limited natural light. Both lean blue, so they'll behave similarly in mixed or changing light conditions. The ΔE 8.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

Blue Note vs Dock Blue in Real Spaces

3 real rooms side by side. Blue Note and Dock Blue 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

In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The brightness difference is modest but present — Blue Note gives the walls a little more lift.

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.
