The type of watercolor paint you should use depends on your personal preferences and the effect you want to achieve. There are two main types of watercolor paint: tube and pans. Tube paint is creamier and more liquid. It can be used directly from the tube or mixed with water on a palette. It is mainly used in large formats. It allows you to obtain intense and vibrant colors, but it also dries faster inside the tube and can waste more paint. Cake pans is more solid and comes in small rectangular containers. It must be moistened with water to activate the pigment. It allows you to obtain softer and more transparent colors, but you can also achieve intensity with several layers. It has the advantage that it preserves better and can be reused. Both types of paint have their advantages and disadvantages, so the best thing is to try them and see which one you like best. You can also combine them with each other to obtain different results. The important thing is that you choose good quality paints, that have a good concentration of pigment and a good light resistance. Some well-known brands are Winsor & Newton, Van Gogh, Sennelier and Schmincke.
