Linda asked about the pigments I use in my watercolors. When I first began I used Winsor Newton paints, and because of my comfort with them have continued to use them almost exclusively. I am far from being a purist and will select any color that I think will work, often mixing them on the fly as I paint. Over the years the following palette has evolved, and I continue to use it, with only occasional variations.
Not shown here are Indian Red (for brick work), Blue-black, and Indigo which I will add to a mixture when I feel it is needed.
I will frequently mix green directly on the paper, adding indigo or blue black for the very dark greens.
For architectural work I will often highlight and/or define edges with colored or pastel pencils.
