I Repeat....

Repetition is necessary to give a painting unity.  In this painting of Pratt's Island lobster shacks, I'm particularly happy with the repetition of colors throughout the surface. It's pretty easy to spot the repeated oranges, violets, and yellows.  Some are pure, some are more neutralized, but they are included at various locations on the page.  This is why it is important to work on the whole page at the same time. 

 It is also easier if you work wet into wet.  Hard edges tend to isolate colors instead of integrating them.
Try to be conscious of repeating color in the early stages of your painting when areas can be kept soft.
