Hi,
Is there a JOSM icon style guide? What elements should be used to depict
different actions? E.g. I want to express move, that would be crossed
arrows like in the move map mode icon, right? Arrows in all directions
is zoom in/out or full screen. Do colors have a meaning?
There is not such a written guide about elements/colors. But some things
are obvious, like green color of download/upload arrows or the red nodes
in the Tools menu. (The core icons have evolved over the years so they
are not consistent in all cases/details either.)
What are
recommended page sizes for map mode icons and menu icons?
For map view icons 16px, for gui icons usually 24px (which is the size
in the toolbar).
Are there recommended icon sets that can be used as reference and that
have the right license to copy items?
A lot of core gui icons are based on tango
(https://commons.wikimedia.org/wiki/Tango_icons) and gnome
(https://commons.wikimedia.org/wiki/GNOME_Desktop_icons) icon sets. The
most core icons are GPL or PD licensed so they should easily be used in
a plugin. More information about icons licenses see the icons section in
https://josm.openstreetmap.de/browser/josm/trunk/CONTRIBUTION
