Controlling columns in a view on a black background is not something that can done easily out of the box in SharePoint with existing themes. In order to make columns show up as white text on a black background, you can use a calculated column with a DIV as follows.

=IF(Attendance=”Not Attending”,CONCATENATE(“<DIV style=’color=white’>”,”Not Attending”,”</DIV>”),CONCATENATE(“<DIV style=’color=white’>”,Transport,”</DIV>”))
