Expensive watercolors can be of higher quality and have more textured or durable, but whether they are worth the cost is a matter of personal preference and budget. Some artists may prefer to invest in a small set of high-quality paints and use them sparingly, while others may be happy with a larger set of lower-quality paints. It's also possible to find good quality watercolors that are not too expensive, so it's worth doing some research and testing different brands and colors to find what works best for you.
