Can I set helpers or positions to be a certain color?
Helpers and positions are not set to colors, but shifts are - a color can be set for each shift and it will retain that color when Imported into a new week, regardless of who is assigned to the shift. You can manually change the color of each shift based on the Helper helping by clicking the shift and changing it (or using the Multi-Shift Edit view). If you later change the assignment, the color would also have to be changed.
You can set category default colors which allows you to choose the category when adding a shift and the color is pre-populated for you.
You can color the shifts and they retain that color from week to week so that when you use AutoFill the color is the same. It is not related to who is assigned.
Since Helpers can sign in and get their schedules and you can view the schedule using many schedule views that break down by Helper (ex. By Helper, Graphical, Availability etc.), our system does not currently allow for controlling shift colors by the helper helping. Normally colors would be used for indicating the Helper was late or to indicate the location or position of the shift, etc.
