Word description Calls quotation with output-stream wrapped in a formatter that translates text attributes and colours into ANSI escape codes suitable for use on a text terminal.
The formatter supports all the text attributes implemented in io.streams.escape-codes, and maps RGB colours to the 16 ANSI and AIXterm colours -plainandbrightversions of black, white, RGB, and CMY. On terminals that report support fordimorhalf-brighttext, that will be used to produce an additional 8 darker colours for foreground text.
Note that since the ANSI and AIX palettes, and the exact behaviour of dim, are not standardized across terminals, the colour mapping used is an approximation and may not select optimal colours on all terminals.
