Have you noticed that all the other dresses are the same colour?? you can quite easily blend two different toneS of the same colour together...contrasting down in shade until you reach the shade in which you desire...However the dress that Claire Danes is wearing is blocks of colour the dont mix together gradient wise....thats why the designer has blurred it to make the tones look softer and more chic as a pose to two big panels of colour.Because of this the colours actually go together.
