What this colour is good for
- A neutral reference when checking for a colour cast or judging white balance by eye.
- A comfortable full-screen background for writing, coding, and reading.
- Revealing dust and smudges without the harshness of white.
Not all panels render #808080 the same way. If a gray screen looks greenish or pinkish, that is your display's tone curve, not the page.
Frequently asked questions
Is #808080 the same as 50% gray?
In sRGB code terms, yes — it is the midpoint of the 0-255 scale. Perceived lightness is a different matter: most people see it as roughly 21% luminance.
Why does gray feel easier on the eyes?
Because it removes the high-contrast glare of a white field while keeping enough brightness to read. It is the same reason dark-gray reading themes are popular.
