excel fillin color

Fill-in color does not show on worksheet while working on the sheet only in
the preview Have I turned off a switch or what needs to be done?

The high contrast setting may be turned on. There's information in the
following MSKB article:

OFF: Changes to Fill Colour and Fill Pattern Are Not Displayed
