It would be helpful if the background color for Canvas gradebook columns could be set by the user.  Different categories of grades (quizzes vs homework vs labs, etc.) could be color-coded to improve accessibility.  

The current assignment-status colors could be modified to make the background color darker or adding a darkened box around the assignment for different situations (late, missing, etc.)

If both the background-color and grade-status options can't be implemented simultaneously, then it would be nice to have the option to choose between them.  Currently, for me, the column background colors option would be more useful than the grading-status colors option.

Thanks
