How to Remove Header Image Opacity in Oblique

If you don't like the header image opacity and want it to be clear then you can add the following CSS to your WordPress. In case you don't have a CSS plugin, we advise you install  Advanced CSS Editor plugin and follow the instructions. In Appearance -> Customize -> Advanced CSS Editor add the following code:

.overlay {
opacity: 0;
}

The above code will remove the header image opacity, but if you want to keep it and just change the overlay color then you can use this code:

.overlay {
background-color: #428bca;
opacity: 0.3;
}

You can change the color values to what you wish, as well as the opacity value.
