How to colour a blank cell

Hi,

When a students doesn't submit an assessment task for whatever reason they need to be followed up. I therefore want any blank cells in my markbook (indicating that I don't have a mark because the students owes me assessment) to be bright red so I know who I have to follow up. I tried doing this by adding a blank cell to my custom grade type and selecting red for that option. However, when I go back to my classes, the blank cells are grey, not red.

Is there a way of doing what I want?

Hello Shull,
I'm afraid that you can't apply a colour automatically to a cell that is empty in the current version.
We'll keep that in mind for our next major update though .
