Watercolor artists, if you haven't tried Daniel Smith paints yet, you're in for a treat! This Phthalo Blue (Green Shade) half pan is seriously vibrant stuff. As a Series 1 color, it's more affordable but still has that incredible Daniel Smith quality we all love. The transparency is amazing, lightfastness is excellent (that's I Excellent for you technical folks), and it's highly staining without granulating. What does that mean in plain English? This blue is crazy intense, won't fade over time, and gives you super smooth washes without speckling. The hand-poured pans are rewettable like a dream - just add water and you're ready to paint. Whether you're mixing greens for landscapes, creating water effects, or just need a reliable primary blue in your palette, this Phthalo Blue delivers rich, creamy color that behaves beautifully on paper. It's one of those workhorse colors that every watercolorist should have in their collection. Trust me, once you experience the pigment load and quality of Daniel Smith, it's hard to go back to student-grade paints!
