Change the product display font color

This is currently what it looks like

I've been searching how to do this but currently I can only find how to change the font color in the product listing.

I would like to change the font color and put a bottom border underneath,. Also i would like to increase the padding after the title

to look something like this



Any Ideas?

I figured it out

all the parts that need to be edited are here
