If you’re using the Custom CSS, I’m assuming you have the full style sheet copied into the Custom CSS box?

Find this section of code by clicking CTRL+F “readmore”.

/* Readmore */
a.readmore, a.more-link {
	color: #fff;
   display:inline-block;
   border: 1px solid #466282;
   background-color: #5f85b0;
   padding: 5px 25px 0;
	-webkit-border-radius: 19px;
	-moz-border-radius: 19px;
	border-radius: 19px;
	height: 30px;
	margin-bottom: 22px;
}
a.readmore:hover, a.more-link:hover {
	background-color: #577da7;
}

I changed mine to read like this:

* Readmore */
a.readmore, a.more-link {
	color: #BE270A;
   display:inline-block;
   border: 1px dotted #7BA38B;

   padding: 5px 25px 0;
	-webkit-border-radius: 19px;
	-moz-border-radius: 19px;
	border-radius: 19px;
	height: 22px;
	margin-bottom: 20px;
}
a.readmore:hover, a.more-link:hover {
	color: #BE270A;
	background-color: #7BA38B;
}

For the site title, go to your style sheet and find this section:

#site-title a span, #site-title a:hover, #site-title a:focus, #site-title a:active {
	color: #5f85b0;
}

Change the color to whatever you want. Here’s a good link to hex colors: http://www.color-hex.com/

Hope this helps!
