It is generally assumed that more experienced artists or those who paint professionally like designers, illustrators, and commercial artists might want to invest more in better-quality paint, and so designer sets are usually top-end, durable, smooth, and vibrant for the very best results. Beginners or those who want to experiment with gouache as a hobby, might not want to spend a lot of money on their first set, so those sets are typically of a slightly lower quality. Beginner sets also sometimes have less color variety, because beginners are mostly advised to experiment with a few primary colors to see how gouache behaves and how to mix and match these staple colors for different tones and effects.
