I did install the latest version and tried to have the coloured display. But I guess that I need some further instructions on how to activate the coloured display.
To me it seems that the 'from language' is one colour and the 'to language' is another colour. But I do not see different colours for pronunciation etc.
I tested with CEDICT and Freedict English-German.
Attached is a screenshot from the WebApp which shows colouring on CEDICT. I could not make a screenshot from Android (to my understanding screenshots cannot be made easily on non-rooted 2.3 Androids).
