Need help choosing watercolors for your travel or field palette? Start by accepting that there is no perfect palette. Your watercolor choices will change over time. As you discover new art supplies and colors you may add them to your palette while removing others that you never use. As you add or delete colors from your palette, consider paint quality, lightfastness, staining, granulation, transparency, and single pigment vs. mixtures. I look for colors that do not fade in the sun (very important), are non-staining, and are transparent. I also prefer colors that contain a single pigment rather than prepared mixtures. Not all watercolors are created equally. Use high quality paints from the beginning and you will make your work much easier. Low quality paint will respond unpredictably and will make it more difficult to achieve intense colors or deep values. I use paints manufactured by Daniel Smith (DS) and some artist grade Winsor & Newton (WN). Each pigment has an alpha-mumeric code that you can use to help you keep track of similar pigments made by different manufactures or understand the ingredients of mixes. Handprint.com is the most in depth analysis of individual colors available, an invaluable resource.
Just as a photograph or couch fades in the sun, so do watercolors. Some colors fade more easily than others and should be avoided. Start your color selection by eliminating all such “fugitive” colors. For this reason I avoid Alizarin Crimson, Rose Madder Genuine, Opera Pink, and Aureolian (Cobalt Yellow). Do your own lightfastness test by painting strips of all your colors and cutting the page in half. Put one side in a dark drawer for three months while the other half hangs in a sunlit window. Compare the colors after three months. If you can detect a change in color, either lightening or darkening, look for a new pigment. Some colors stain the paper and cannot be lifted out. Others sit as granules on the top of the paper surface and can be lifted out with a damp brush. This makes it possible to correct mistakes or add whites back into a painting. I prefer non-staining colors as a rule, but often I need to incorporate more staining colors to get a better range of colors. Paints may contain heavy particles that concentrate into patterns on rough paper as the paint dries. This is called granulation, and it can create beautiful and surprising effects. If you like (often pleasant) surprises, you will like granulating paint. Wherever possible, I use transparent watercolors which allow me to layer coats of paint and maintain the brilliance of watercolor.
Some artists prefer to limit their palette to a few primary colors and then mix the rest of their colors. This is excellent training in mixing colors. I prefer to take advantage of the array of colors created by grinding chemicals or earth materials into paint. I can combine these single pigments to mix the rest of my colors. This is not “cheating” or taking a shortcut, but instead you are taking full advantage of the characteristics of different pigments. Paint suppliers also sell their own mixes of multiple pigments. These are less useful for mixing, but often convenient. If your palette is limited, focus on single pigment colors rather than pre-made mixes.
