Bug 87933

In Calc, the Grid lines have a gray color (~Gray 3.5 - #c0c0c0) and the automatic page breaks have a slightly darker gray color (Gray 6 - #808080) and this small color difference isnt very easy to see.

How other spreadsheet applications color their cells and page breaks.

MSO Excel 2010  : Grid Line #dadcdd, Page Break #000000 (Black) with dashes
MSO Excel 2003  : Grid Line #c0c0c0, Page Break #000000 (Black) with dashes
WPS Spreadsheet : Grid Line #d7d7d7, Page Break #000000 (Black) with dashes
Quattro Pro X7  : Grid Line #c0c0c0, Page Break #0000ff (Blue)
Calligra Sheets : Grid Line #c0c0c0, Page Break #ff0606 (Red)
Gnumeric        : Grid Line #c7c7c7
iWork Numbers   : Grid Line #a6a6a6

The use of dashes in MSO and WPS make it easier to distinguish that the page breaks from cell border colors, and most users dont set cell border styles (aka the dashes). Quattro Pro and Calligra have a color showing this difference, though you have to go into the View menu to turn on this page breaks view, which we also have called page break preview and it uses a dark blue color (#000080) for page breaks.

So i'd like to suggest the following:

1a) We stick with the gray page break color, but change grid lines to Gray 3 (#cccccc) and page breaks to Gray 7 (#666666) to solve the visibility issue and also add dashes to the page break.

or

1b) We go with the lighter blue color compared to the dark blue color from page break preview and add dashes to it.

The changing of the color seems to be easy to achieve as it is in Tools > Options > Appearance, while adding dashes would likely require some dev work.
