Currently it is just theme based, whenever the user changes the theme accordingly the color changes. Not for any specific preference option for this right now, But if we want that we can add.
And if i am not wrong you are talking about this #7863 . If this is the issue then I can work together on both.
Please check the updated attached screenshot for an alternate background color of table rows. The images also shows alternate row color with some selected rows color from the table.
I think that looks good. Are you making it a preference, so users that prefer non-stripey grids can keep the current look?
Whilst you're hacking on that, I believe there is another ticket (which I can't find right now) about changing the colour of the row number column to give it better visual distinction from the data columns. Probably worth working on that one at the same time?
