Help: Canard Theme

Hi, I have got 2 questions about editing this theme. Firstly, I am putting a picture of the page so you can see what I’m talking about. Unfortunately I can’t give a direct link to the site since it is still on localhost. Here is the link to the screenshot: http://i.imgur.com/KnZ08Z3.png

1. I have managed to remove the “Featured image” in the post page but the title is transparent, I would like to make it simply black. However hard I tried, I failed to edit the color, how can I do it?

2. I have managed to change the site background color to light grey but the main menu(the one with “The Aegean, Istanbul etc.) background is still white. How can I change it to the site’s color?

Thank you.
