For budget-friendly beginners, start with a basic student-grade watercolour set of 12 colours in tubes, two synthetic brushes (size 8 round and 1-inch flat), a pad of 140lb cold-pressed watercolour paper, and a simple palette with wells. This setup costs under $100 and provides everything needed to begin learning. The mid-range option upgrades to artist-quality paints in primary colours plus earth tones (about 8-10 tubes total), adds a quality size 12 round brush, upgrades to 300lb paper, and includes natural sponge and masking fluid. This kit offers noticeably better performance for techniques like wet-on-wet and lifting. The premium setup features professional-grade watercolours, handmade paper, natural hair brushes in multiple sizes, and advanced accessories like ox gall medium and granulation medium. While expensive, this level provides the ultimate painting experience and supports the most sophisticated techniques. Each tier builds logically on the previous one, allowing you to upgrade components gradually rather than replacing everything at once.
