Congratulations on finishing your tree!

The colour change means that you need to keep practising. If you don't practise, you will forget things. For that reason, the system shows you the things that you might forget.

Felicitaciones por terminar tu árbol de inglés ;-)

DuoLingo uses the concept of Space Repetition Method (spanish article link).

When the circles, called lessons, turns colored, it means you've "forgotten" them and it's time to re-learn them.
