Watercolor Paintings

I have been doing watercolor paintings since my college days in Southern California. I have always loved going back and forth from oils to watercolor as you are taught to work in opposite manners. In watercolor the theory is to leave the paper as the white in the image. This requires working from light washes to the dark shadow colors. In oils you start with dark washes and the final layers are the highlights.

By going back and forth between the two mediums it challenges my thinking and has me thinking "why can't I paint oils like watercolors?" In watercolor it requires painting with white. (OMG!) Which in purist watercolor circles is heresy. Fortunately I am not a card carrying purist so that doesn't matter to me.
