Horizontal bands of color progress through warm oranges and reds, cool blues and blacks, and muted transitional tones, creating a systematic study of chromatic shifts. Thin parallel lines layer across each stripe, suggesting a methodical cataloging of pigments or hues arranged with precise, almost scientific intention. 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.
