Get the ANSI color palette in use by terminal {buf}. Returns a List of length 16 where each element is a String representing a color in hexadecimal "#rrggbb" format. Also see term_setansicolors() and g:terminal_ansi_colors. If neither was used returns the default colors.

{buf} is used as with term_getsize(). If the buffer does not exist or is not a terminal window, an empty list is returned.

Can also be used as a method:

GetBufnr()->term_getansicolors()

only available when compiled with GUI enabled and/or the +termguicolors feature
