The colours on Goals and Steps are a quick visual guide to when things are due.
Red means overdue.
Orange means almost due. A Step goes orange if there are 7 or less days left before finish date. This means a Step will be orange if it is due for completion in one to seven days.
Green means there is over a week until it is due. A Step is green if there are more than 7 days left before it is due.
Black means it is completed.
Grey means there is no finish date set
