Each watercolor pan is hand-poured. Hand pouring pans is incredibly labor-intensive and offers the purest form of professional watercolor half pans. It takes three to four pours over several months of drying to produce each half pan of DANIEL SMITH Watercolor. Cleaner, more transparent and brighter in chroma than Cadmium Yellow Light, this is a high-tinting, semi-transparent organic pigment. Hansa Yellow is considered the 'perfect yellow', offering more control when mixing. Painters admire the purity of this primary pigment and ability to adjust its temperature while avoiding a gray from a hidden complement. Think of a yellow pepper.
