Body Font Colour

Hi,

I’m having trouble setting the font colour for my website. The problem is with iPhones.

When I set the font colour for the body in the customise theme options, it changes the font on all pages on iPhone to that colour, but I have some light backgrounds and some dark backgrounds so I want the font in the light background to be black and the font in the dark backgrounds to be white.

For desktop, iPad, android, I can just use inline css and this will change the font colour to what I need, but iPhones seem to ignore this and just go with whatever the colour is in the customise font settings.

I’ve tried using inline css with !important but still nothing changes

Thanks in advance for any help!
