Description:
Currently Calc's page background follows the page background global setting. This is a problem when that global setting is set to dark, in my case for eyestrain.

I have overcome this for my spreadsheets by creating a template with a lighter background color. But the problem continues when loading spreadsheets from other origins. The resulting color output can be unintelligible, and there is no ready way to rectify it, as the applied colors can be very involved. If I back off the global dark setting, I lose my dark page margins in Writer.

The solution, I think, is to give Calc its own default background sheet color in Settings, completely divorced from the current global setting. Actually, I'm not sure what value that global setting would have, once Calc were divorced from it, if Writer also were given its own page background setting.

BTW, I'm not an advocate of divorce, but sometimes it is necessary. :)

Steps to Reproduce:
1.Change global page background to dark color
2.open new calc spreadsheet


Actual Results:  
3.observe a completely dark page before you, instead of just dark margins.

Expected Results:
Expected only margins to be dark, but there are no margins on calc's screen. Whole screen is dark.


Reproducible: Always
