Viewing fill colors

[TQ North]

I have a lot of fill colors and font colord in my spreadsheets. They show up
in print preview but not in normal view. How can I change settings so that
these colors show up in normal view?

Colors are only missing on monitor, due to High Contrast Accessibility option.
