Exterior Sign in White Oak: Finished | David Fisher, Carving Explorations:

After a lot of research, consultation of folks with exterior sign experience, and personal testing, I went with the artist acrylic paints above, although other very good brands would work as well. These pigments are all from the larger list recommended by Martin Wenham in his book. I’m trying to learn more and more about color theory and practice and Martin is a master. I mixed the brownish color from the first three, and the green from all four. Professional artist colors like these list the specific pigment used, along with the opacity (vs transparency) of each color. Notice the opacity square for each of these pigments is a completely black square, meaning very opaque/solid. Also, all of these pigments have the highest lightfastness rating, so they will be naturally resistant to fading. I thinned my mix just a touch with an acrylic medium to the consistency I wanted to work with.
