Change colour of negative numbers

I’m using Dark mode and Dark application colours, but I’d like to change the default colour red used for negative numbers (to Light Red 2 so that it’s less vibrant and a bit easier to read with a black background). Is there an option somewhere to change this?

I tried using conditional formatting but the font colour is ignored (but I can change other font styles). The default colour red used for negative numbers must take higher precedence than anything specified in conditional formatting, it seems.

Thanks

I have found a workaround as follows, but having an option somewhere to change the default Red everywhere, would be nice to have:

  1. Highlight column with numbers
  2. Right-click, format cells
  3. Near the bottom of the Format Cells window, under Options, tick the Negative numbes red checkbox
  4. Change [RED] in the format code text box to [COLOR53], or any of these other pre-defined colour codes
  5. Click OK
