Hi there,

Can you please send us your site URL first, so we can investigate your site and then get back to you with possible solution. 

P.S. make sure you've disabled the Maintenance/Coming Soon mode

Hi there,

If you are talking about the video in this page, add the following CSS to Custom CSS:

.video-js.vjs-default-skin .vjs-big-play-button {
    -webkit-text-fill-color: blue !important;
    fill: blue !important;
}

Hi again,

The same code will apply to the homepage too, simply add it to the Custom CSS in general or only in that page, if you don't know how to apply custom CSS then follow this guide.
