Duotone colors style reference and prompts

A duotone photographic treatment divides a composition into opposing cool and warm color territories with a crisp straight seam. Saturated teal and blue-green carry the shadow side; golden yellow and hot orange transform the lit side, leaving almost no neutral color. The color division crosses foreground and background alike, making a simple spatial scene read as a graphic design. Natural surface detail remains visible within the tinted zones: subtle volume, fine texture, and small folds prevent the image from becoming a flat poster. The main lighting is soft and frontal; the abrupt border is a color treatment rather than a cast shadow. Large clean background areas frame a centrally placed, closely cropped focal form. The overall visual effect is bold and balanced, built from the tension of two luminous temperatures and one decisive geometric boundary.

A square duotone fashion photograph frames a woman from the chest upward, her face divided by a perfectly vertical line between cool teal and glowing golden orange. The background follows the same division, teal on the left and flat orange on the right, so the color boundary passes through both the person and the space behind her. She faces forward with a composed, slightly distant expression. Her dark hair is gathered into a loose textured updo, with a few softer strands along the sides. The left half of the face sits in blue-green shadow, while the right half is rendered in orange and yellow light. Both eyes remain visible on either side of the seam; the nose and lips are bisected by it, emphasizing the symmetry of the crop. One hand rises near the right side of her neck, its fingers outlined by the warm light. A textured knit or mesh-like garment covers her shoulders, its tiny repeated pattern legible in both color zones. The left shoulder is dark teal against a brighter teal ground, while the right shoulder is orange against a saturated gold background. The photograph preserves natural facial modeling beneath the color treatment: subtle cheek volume, eyelids, hair texture, and garment folds remain visible, even though neutral tones have been replaced. Light is fairly soft and frontal, with a strong color shift rather than a hard physical shadow at the central border. The lower corners darken slightly around the garment, but the upper background stays clean and broad. The overall composition is direct and graphic, letting a single central seam hold the poised figure between two opposing luminous temperatures.
