New Theme Name?

I’ve posted this elsewhere but couldn’t get a single response hence I’m posting it he’re again. Would love to know the UI Theme Name and Syntax Theme for the below picture which is the current one hosted on

It it’s just for representation purposes, something that comes close to it will do to.

The UI theme looks like the One Light. As for the “syntax theme”, this looks like it was coloured in Photoshop or the likes. Otherwise, how do you explain the const declaration varying in colour?
