Reply To: Re: Blog Page Header Background Color

This will change the color to white. Locate .site-header in your css (should be around line 1159)

.site-header {
	background-color: #000;
	border-bottom: 1px solid #ddd;
	left: 0;
	position: fixed;
	top: 0;
	width: 100%;
	z-index: 999;
}

Change #000 to #fff

.site-header {
	background-color: #fff;

To add space to the left of the logo. Add margin-left: 20px; to .site-title a

.site-title a {
    margin-left: 20px;
}
