Separate images overlay

Hi
I have a one page layout on a website i am creating but the separator images are really dull like they have a overlay on them. how do i remove this please?
Thanks

Hello,

Overlay color is default one in theme style.css but it is configurable in theme options as you can see from printed theme css on the page https://www.screencast.com/t/xjBr5SXbvs https://www.screencast.com/t/yx0e6zTul07

If you can’t find the option you can always remove overlay with custom css code:

.overlay {
    background-color: transparent !important;
}

And you can apply the code from Appearance > Customize > Additional CSS field.

Best Regards!
