Youtube Playlist Background

Hi,

If you mean the background color here

That could be changed to white with a code since there are no dedicated options for it, the text will be invisible however

So the color of the text should be changed as well as the active and hover colors, this would be the result

If that is what you wanted, enter the code in Theme panel->Custom CSS section

.td_wrapper_video_playlist .td_container_video_playlist {
background-color: #fff;
}
.td_wrapper_video_playlist .td_video_title_and_time .td_video_title {
color: #000;
}
.td_wrapper_video_playlist .td_video_currently_playing .td_video_title,
.td_wrapper_video_playlist .td_click_video:hover .td_video_title{
color: #fff;
}
