I would use states to make this happen, too.  Add a state and for that effect, make the image black and white using the image color editing (or another dimmed color version), and then overlay a text box - all within the same state.  Then create a trigger to change the image to that state when the learner does whatever you want them to do in order to dim the image.

Sorry Tom I should have explained that better.

In addition to the inbuilt Storyline states you can create your own custom states.

Heres a quick video on how I did that
