Question

Is there a way to change the Background color into xlNone,
for example to the entire sheet. I see that you can put a background image…
But how can you change the color for all cells in the sheet?

Answer 1

You can do this quite easy with this code:

Public Sub Demo()
  'set color
  WorksheetName.Cells.Interior.ColorIndex = 1 'black
  'clear color
  WorksheetName.Cells.Interior.ColorIndex = xlColorIndexNone
end sub

Or if you don’t need VBA, just click at this little icon in the corner:

and select a color, or to use no color – using right click menu or ribbon menu.

Just because of the other answers, I want to remind – it is not necessary to use selections! This is bad macro-recorder style. There are only few occations, where using selections is necessary or a good idea. You can always just use a specific range.
