About Dim Gray
Dim gray, #696969, is medium-dark gray — the CSS-named neutral just darker than middle. It is the reliable workhorse gray for secondary text and muted UI: present but never loud.
History
Dim gray is a purely functional name from the X11 color list; it became a staple secondary-text and icon color across the web precisely because it is unremarkable — gray that does its job and disappears.
Psychology
Dim gray reads neutral, understated and functional — gray with just enough depth to structure without demanding attention. It is interface plumbing made visible.
In design
Dim gray (#696969) is the reliable muted-text gray: passes AA on white (5.9:1), ideal for secondary copy, captions and icons. Pair with any accent; it is pure supporting neutral.
In culture
The "666666" of a thousand stylesheets, dim-gray captions and timestamps: the humble neutral that quietly carries half the web’s secondary text.
