EPG COLORS?

If you're tryingt o edit the files in the default Confluence or Estuary skin that is included in LE - you won't find it as it is built into the kernel. You will have to install another skin first and then edit that set of files.

If you want to use Confluence or Estuary - you can install a mod version of those files from Kodi Community Forum - Confluence or Kodi Community Forum - Estuary then you will find the files in your userdata folder.
