Navy is the darkest blue that still clearly reads as blue. #000080 is dim enough to use in a dark room without wrecking your night vision, but bright enough in the blue channel to expose blue subpixel problems.

What this colour is good for
- Low-light background for a dark room, nursery, or night-time desk setup.
- Testing whether the blue channel is uniform at low intensity.
- A calm, deep background for presentations and dark-theme mockups.
Deep navy is easy to mistake for black on an uncalibrated display. If it looks black, your display is crushing shadows — check with a grayscale ramp.
Frequently asked questions
What is the difference between navy and black?
#000080 has a full blue channel and no red or green. It reads as a deep blue that still shows some detail, where #000000 is the absence of light entirely.
Is navy good for sleep?
It is darker than most colours but still contains blue light, which suppresses melatonin. If sleep is the goal, red is the better choice.
