| Flag | Description |
|---|---|
| 24-bit-color | Enable 24-bit color support. Note that this feature is unofficial, may cause visual glitches due to the fact there is no termcap/terminfo definition for rxvt-unicode-24bit yet so it is necessary to use the one for 256 colours, visibly increases memory usage, and might slow urxvt down dramatically when more than six fonts are in use in a terminal instance. |

| blink | Enable blinking text |
| fading-colors | Enable colors fading when off focus |
