waycolor:background:foreground:text:textcolor
The waycolor must always be present but is ignored for this map. Furthermore you must specify a background, although you can leave the field empty. Next follow a maximum of two different foregrounds. In the end you may optionally add a small reference text to be added on top. The color of the text must always be specified. Note that waymarkedtrails will ignore reference texts when they become to long. How long the text can be depends on the chosen backgrounds: the hard limit is 4 characters, diamond-shaped background only take a single charaters, stripe- and bar-shaped backgrounds take no reference text at all."  Is there a map that does not ignore the content of the first field?
