Some numbers are difficult to see if the background gets too dark. The fonts are set to automatic, but that does not help. Given that I won't know which cells will be coloured to that degree on conditional formatting, is there a simple way to match the font white if the cell is too dark automatically? I have many of those in multiple tabs, therefore a solution that can fix the whole spreadsheet would be ideal.
Hopefully it's something simple I'm missing. Thank you in advance :)
