transparency

hi to everyone!

help me please to configure my moc to be transparent, i can find nothing on this site to make me understand how to do this except the comment for screenshot. it says: after switching to on-menu mode, configured with transparent theme.

i'm a beginner to linux and to moc, so please excuse me if you find this question stupid. what is on-menu mode? do i need to install some transparent theme individually?

i have configured my console to be transparent, but moc in it is usual blue, so my conclusion is that transparency needs to be configured separately...
