Changing the colour of the red in Lupercalia

Hi,

I know that the “Crimson” red used in the Style sheet for Lupercalia appears to be #DC143C. I would like to change it to #c92228 if possible but do not know how to do this in the style sheets, nor do I know where to find this.

Also, in bloglovin feeds the photos don’t seem to show like everyone else.

Is there also any way of finding out what font size the headers typically show? Just trying to match an offline document to the style.
