Sounds reasonable to me. And I especially like the approach to use the 
same color but different alpha values. This seems to me to be the more 
intuitive approach, since it avoids that users have to learn colors but use 
the meaning that a high saturation is better than a low one.
Though, I am unsure about the percentage value and the color of 
unlearned words. IMO it is hard to understand how the value is related to 
the bar. If I understand it correctly, the last bar element visualizes the 
untried words and the second last box the yet unlearned but tried words.
Could it be useful to put the percentage value always directly after the 
fifths box, mark the sixth and seventh box in a different color but again 
with different alpha values?
That would at least stress the difference between learned and unlearned 
words and give an indication how the percentage value is computed.
