Pan watercolors are a great supply for home art time. They are versatile, come in a variety of colors and are easy to store. My favorite pan watercolor brand is Prang. They come in sets of 8 and 16 colors, have a good, vibrant pigment and are semi-moist which means they are easier to get the paint wet and ready to paint with. Prang also makes a washable set, however the pigment is less brilliant and tends to fade over time. Here is a link to the set I use. These paints can be found at craft stores, box stores, and online and the price can vary a lot. Look for them in August and September for the best prices. I have also used the Crayola watercolor set with students and found the pigment to be satisfactory and the paints easy to use. Avoid super inexpensive watercolor sets. They don’t take on water easily because of a higher wax content and sometimes the pigment is so inferior that the colors are pale and inaccurate. It’s frustrating to want to paint purple and the color you get is pink or magenta.
