Its not that easy to config mRemoteNG custom color themes, not like XShell which is really convinent. There are many options to select and I will give two favorite one.
Step 1: create a reg file such as default.reg with content like below example.
Step 2: double click the file and confirm it.
Step 3: we can find the new settings under PuTTY session settings in Connections panel.
