Space itself does not have a single color; most of it appears black to human eyes, with points and patches of color only where there is light (stars, galaxies, nebulae).

What “color of space” means

Color is a perception created when light of certain wavelengths reaches our eyes and the brain interprets it, so an “empty” region of space with almost no light just looks black. When enough starlight from all directions is averaged together, astronomers estimate the universe’s overall color to be a very pale whitish‑beige, sometimes called the “cosmic latte.”

What astronauts actually see

Astronauts in orbit see a very dark, almost pure black sky with sharp white stars and no blue background, because there is no atmosphere to scatter sunlight. The most colorful thing they see is Earth itself, with bright blues, greens, and whites standing out against that blackness.

Why space photos look so colorful

Colorful images of nebulae and galaxies often use long exposures plus color mapping to highlight different gases and wavelengths, including light outside what humans can see. These colors represent real physical information (like hydrogen or oxygen emissions), but many images are enhanced or “false color,” so they are not exactly what the eye would see from a spaceship window.
