A stack of concentric eye forms in rainbow hues transitions from warm red at the top through yellow, green, and cyan to deep navy blue at the bottom, each layer outlined in clean lines that create an optical tunnel effect. The geometric precision and color-field progression convey both visual clarity and psychological depth, evoking the sensation of focused perception narrowing toward a single point. 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.
