Customisation Tweaks

I was wondering if somebody could provide me with codes to achieve the following: Change the colour of this page border: http://www.everyhomeisacastle.com/about-2/ Achieve the same effect on this page, and customise the colour of all comment boxes: http://www.everyhomeisacastle.com/contact-2/ And finally I'd like to change the title colour and border of the first box on these pages: http://www.everyhomeisacastle.com/category/diy/
