A meticulously organized table of blue pigment samples arranged in a grid, each accompanied by handwritten notes identifying animal, vegetable, and mineral sources for the colors. The palette ranges from deep indigo and navy to softer slate and dusty blue-green tones, rendered with careful watercolor swatches against cream pages marked with precise typographic labeling in an early nineteenth-century scientific style. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
