Hi,
Graphics colors are actually the user' "taste" or options matter...so, you may easily change the colors from Input Spreadsheet / "Plot Properties" button.
Once you've finished the settings change, the new settings remain valid for any *.CAESAR II file regardless the *.CFG file option.
CII old versions used to have dark red/maroon default color for restraints, while pipes were colored in blue.
Maybe someone else would like pink or orange color for restraints, so why to change the settings (again!) to a specific color? It really doesn't matter...
Regards,
