Moreover, a single colour definition in XRC may contain more than one colour,
separated by `|` (pipe symbol), with the first colour used by default and the
subsequent colours in specific situations. Currently the only supported
alternative colour is the colour to be used in dark mode, which must be
prefixed with "dark:".
It is recommended to provide both light and dark values when not using system
colour names (that already adapt to the dark mode), as it's rare for the same
colour to look well in both light and dark mode.
Some examples:
@code
<fg>red</fg>
<fg>#ff0000</fg>
<fg>rgb(255,0,0)</fg>
<fg>rgb(192,192,192)|dark:#404040</fg>
<fg>wxSYS_COLOUR_HIGHLIGHT</fg>
