Blog Title Colour

Hello, I have changed my background from the default black to white. The blog titles in the blog archives section seem to be set to white as default and I am unable to change this colour. I can only see the headings when I hover over it and it changes to orange? Are you able to provide a code to change the colour from white to black? Can you also provide a code to change the hover colour from orange? Our url is: https://wafflesandlamingtons.com/travelblog/ Thanks, Theo.
