Currently working on this painting.  I am always fascinated by tree roots and how they grow into the water like they are so thirsty.  I'm trying to play with color and the very subtle colors I want to exaggerate.....makes painting interesting for me.  It's not been the easiest picture to paint, although it is so fun working with this palette.  I'm using some raw sienna, antwerp blue and burnt sienna, viridian and violets made with cobalt blue or ultramarine blue and brown madder.  Maybe I'm using too many colors in one painting, but I love how they all work together.
