I have a GANTT planning application where each activity or job has a status. In the next release users asked for the possibility to add colors to activity statuses however I need to choose a standard coloring for the pre-configured activity statuses.
The possible activity statuses are:
OPEN, CANCELED, TO BE CONFIRMED, DEFERRED OR POSTPONED, SUSPENDED, CLOSED
I would like the colors to be intuitive, and so possibly to imitate some well known and studied interface or program.
I would also like to avoid the red, it would indeed give the impression of something wrong and would grab too much attention while instead all statuses above have to be all perfectly legal. I want also to avoid people not setting the status to some state because the color might give an idea of something not ok.
These are the colors I came with just by intuition:
to be confirmed and postponed are similar color on purpose.. they both should be similar to an open activity in my opinion and grab some attention.
