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. Constructed from woven polyester with a soft microfiber lining and a sturdy zipper, made to order for 13 and 15 inch laptops. Everyday protection carrying an independent artist's work, not another plain black sleeve.
