 ## 256-colors
 
 Chalk does not support support anything other than the base eight colors, which guarantees it will work on all terminals and systems. Some terminals, specifically `xterm` compliant ones, will support the full range of 8-bit colors. For this the lower level [ansi-256-colors](https://github.com/jbnicolai/ansi-256-colors) package can be used.
