Small visual changes (blue color)

I’ve added the key ‘Output’ to the dict colorCodes in order to be able to changes the ‘blue’ color of Theano graph node which is not well visible. Personally, I used the 'Output': '#87CEFA' color code calling pydotprint(…). An alternative correction should be to replace ‘blue’ by '#87CEFA’. It’s up to you…
