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.)

For map view icons 16px, for gui icons usually 24px (which is the size 
in the toolbar).

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
