Changing texts default colour on the whole website

Hi there,
I just need to change the default texts colour for the whole website on Shapely. I checked all the customise options for changing colour but changing texts is missing. I even could not find a similar question in the support forum so am asking for your help. The default original colour is very bright grey hardly readable over a white background. The title is not my question only the main texts.
Best
