Coloured Overlay

Could you please provide a link to your site? Thanks!

The color overlay for header images in the Kelly theme is setup with the following CSS in the theme:

.header-background {
	background: rgba(6,156,136,0.75);
}

You can remove that background color by adding this to a custom CSS editor such as the one that comes with Jetpack:

.header-background {
	background: none;
}
