Can't find where to change Cyan color

I have read the other threads and the FAQs and applied the instructions but I have not managed to change some specific collored areas.

I have changed in:

/ public_html / includes / templates / MY TEMPLATE / css / stylesheet.css

body {
margin: 0;
font-family: verdana, arial, helvetica, sans-serif;
font-size: 62.5%;
color: #000000;
*background-color: #ffffff; / this is supposed to be white */
** }

Even with the above change, if you check my site www.poolpresent.com you will see at the right bottom of the site the cyan color.

Also I would like to change the Orange color which appears on the right side of the page between the boxes.

Finally, I would like to change the Brown color on the Navigation bar where is says "Home".

I have been looking and testing for days in different parts of the code without success. Any help as to which parts of the code in the stylesheet.css would greatly be appreciated.

Thank you,
Asriel

Finally, I would like to change the Brown color on the Navigation bar where is says "Home".

#navBreadCrumb {

}
