Faint/dim (SGR 2)

Category: sgr · Tags: ECMA-48 Standard, VT100 · Specification ↗

SGR 2 renders text with reduced intensity (dimmed). The sequence is ESC [ 2 m. Commonly used for secondary or de-emphasized text in TUI applications — status bars, disabled items, or metadata. Faint is reset by SGR 22, which also resets bold (SGR 1). There is no separate reset code for faint alone. Most modern terminals support faint rendering, typically by reducing the alpha or brightness of the foreground color.
