Yes, you can put your tube watercolors into pans. This can be a great way to save money and space, as well as to have more control over the paint. It is important to remember, however, that not all tube watercolors are the same, and some may not work well in pans. If you are unsure, it is always best to test a small amount of paint before committing to this method. To pan your watercolors, start by adding a small amount of water to each color. Then, using a palette knife or other flat tool, carefully transfer the paint to a pan. Once all the colors are in their pans, add a bit more water and mix well. Allow the paint to dry thoroughly before using.
