# Organic Color Field Line Poster > Edit each user-supplied photograph into its own 3:4 premium poster with truthful photography above and a light continuous-line interpretation breathing through 2–4 source-derived organic watercolor color fields below. Use for intimate, healing, romantic, restrained picture-book and editorial work; do not use for ordinary line-art tracing, hard vector blobs, fixed pastel palettes, cartoons, commercial typography, or multi-photo collages. - Skill: `goodchengwang/organic-color-field-line-poster` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add goodchengwang/organic-color-field-line-poster` - Raw SKILL.md: https://api.skillmd.com/api/skills/goodchengwang/organic-color-field-line-poster/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Design & Media - Author: goodchengwang (https://skillmd.com/u/goodchengwang) - Updated: 2026-09-22 - Page: https://skillmd.com/skills/goodchengwang/organic-color-field-line-poster --- # Organic Color Field Line Poster Use the system `imagegen` skill and image-generation tool. Treat every uploaded photograph as the edit source. Distill one meaningful relationship into a few breathing lines while organic color fields carry its emotional flow. ## Output contract - Produce one independent raster poster for every uploaded photo. Never combine photos into a collage, contact sheet, comparison layout, diptych, or shared canvas. - Use a 3:4 portrait canvas with one exact horizontal 50/50 division. Keep truthful photography in the upper half and the line-and-color-field artwork in the lower half. Do not let either medium invade the other. - Preserve immediate correspondence through the hero's posture, proportion, direction, relationship, decisive contour, and a few identity cues. - Use warm paper white, fine black/gray line, two to four organic source-derived color fields, large blank space, and very sparse English type. - Return every poster as a separate image. Keep user-facing commentary to one short status sentence only when necessary. ## Preserve the photographic upper half Keep the source recognizably photographic. Preserve subject identity and count, anatomy or construction, proportions, emotion, pose, silhouette, direction, spatial relationships, real materials, natural light, and the original color atmosphere. Apply only restrained art-magazine, independent-publication, or exhibition-photography color correction. Do not redraw, vectorize, beautify, materially relight, or apply line art, color fields, typography, or graphic overlays to this region. Crop deliberately for the upper half. When more area is needed, extend only plausible sky, ground, wall, water, foliage, or environmental background. Never stretch, warp, mirror, duplicate, or redesign the subject. ## Identify one emotional relation Before prompting, privately identify: 1. the one hero subject or inseparable relationship carrying recognition; 2. the most meaningful emotion, action direction, spatial relation, or metaphor visible in the source; 3. the decisive posture, gap, touch, gaze, contour, axis, path, or movement that makes it legible; 4. three to six identity cues that must remain after line reduction; 5. the dominant emotional color and one to three supporting source colors; 6. the negative spaces and directional areas that can become organic fields; 7. one extremely short English word or phrase and, only when needed, one tiny supporting note. Write one plain proposition: `[subject or relationship] + [action/state] + [feeling or implication]`. Do not expose this analysis or repeat the user's design brief. ## Reduce the source by subject type Choose what the line must preserve: - people: posture, gaze, gesture, contact, distance, clothing rhythm, and relationship; - animals: action, balance, species-defining contour, alertness, and relation to ground or companion; - plants: growth direction, stem/branch flow, leaf or bloom mass, lean, and surrounding air; - objects and vehicles: key structure, function, orientation, support, and movement; - architecture and interiors: proportion, openings, boundary, axis, enclosure, and spatial interval; - landscape and nature: horizon, contour, flow, terrain, distance, light direction, and one decisive event. Delete realistic surface description, repeated detail, minor anatomy, background clutter, and complete contour segments that the viewer can infer. Avoid using the same face/profile/hand motif for every source, and avoid simplifying nonliving subjects into cute characters. ## Draw with continuous but incomplete line Use a small family of fine, natural, near-continuous lines. Let them show subtle pressure changes, pauses, restarts, and hand-led rhythm. Use: - omitted contour passages that the eye completes; - lines connecting related subjects or parts; - slight offsets indicating distance, memory, or movement; - extensions following gaze, growth, direction, or action; - overlaps and crossings at meaningful contact; - stopped or unfinished endings holding quiet tension. Keep enough recognizable structure for immediate source correspondence. Use only a few small supporting strokes. Avoid mechanical tracing, complete outlines, repeated sketch contours, hatching, dense line detail, arbitrary decorative curves, rough scribbles, perfect vector smoothness, and black filled masses. ## Compose one relation in soft silence Place the hero according to the source's posture and motion. It may be offset, cropped, suspended, lightly spread, or held near one edge. Preserve one center of gravity and one reading path. Use large blank paper as active space for distance, intimacy, pause, continuation, air, or emotional aftertone. Build rhythm through line density, gaps, approach, separation, crossing, and direction. Avoid mechanical centering, complete scene drawing, equal visual density, many motifs, decorative borders, complex background elements, and template-like minimalist layouts. Present the result as a flat editorial illustration. Do not add a frame, wall, book mockup, desk, gallery room, product card, or presentation setting. ## Build 2–4 organic color fields Extract two to four high-key, low-to-medium saturation colors with the most emotional value and life from the upper photograph. Rebalance them rather than applying a fixed healing pastel card. Assign clear roles: - one principal field carrying the largest emotional atmosphere; - one or two supporting fields shaping movement, distance, or balance; - optionally one very small point field or accent marking the narrative focus. Place fields according to hero contour, action direction, negative space, and center of gravity. One may sit behind the hero, one may extend to an edge, and two may overlap slightly to create a transparent mixed hue. Do not distribute color evenly. Do not use a field unless it alters spatial reading, emotional weight, or the path through the artwork. ## Keep shapes loose and physically diffused Make the fields asymmetric and varied in size. Their edges should combine a few clearer passages with watercolor bloom, pigment seep, uneven diffusion, feathering, and gradual disappearance into paper. Use transparent overlap and paper white for depth. Let the color feel like emotion moving slowly through the composition. Avoid perfect circles, regular ovals, smooth Bézier blobs, hard vector blocks, thick opaque masses, digital gradients, airbrush glow, rainbow overlap, watercolor puddles, and many small decorative spots. ## Translate the source palette faithfully Use warm paper white, black or deep gray line, and the selected two to four high-key soft colors. Preserve the upper photo's warm/cool relationship and emotional identity. Build hierarchy through field area, transparency, overlap, local saturation, and one tiny accent. Keep the largest field quieter than the most important focal color. Avoid fixed blush/sage/blue formulas, candy pastels, muddy gray, dark brown, yellowed paper, neon, equal saturation, complex multicolor mixing, and colors absent from the source. ## Make English text another line Derive one extremely short English word or phrase from the source's emotion, relationship, action, or metaphor. Use a fine loose cursive, single-line handwriting, or an extremely light editorial face. Let an existing drawing line become the first stroke, final stroke, baseline, or connector of the word. Alternatively, align the phrase to a gesture, contour curve, gaze, movement, or blank-space direction. The text may float, bend slightly, be crossed by the hero, or dissolve near a color field. Add only one tiny auxiliary note when necessary. Avoid direct object labels, commercial fonts, large titles, dense copy, decorative lettering, forced romance quotes, unsupported facts, logos, brands, signatures, pseudo-language, or watermarks. ## Compile the image-edit prompt Write one source-specific production prompt per input photo containing: 1. one independent 3:4 portrait output and the exact 50% photography / 50% organic-line split; 2. the upper-half preservation invariants, restrained color correction, crop, and any safe background extension; 3. the core proposition, hero or relationship, posture, action, direction, gap/contact, and three to six identity cues; 4. the exact retained line family, omitted contours, connections, offsets, extensions, crossings, pauses, stops, and supporting strokes; 5. the hero placement, crop/suspension/spread, center of gravity, reading path, line-density rhythm, and emotional role of blank space; 6. the exact two-to-four source-derived fields, principal/support/accent roles, sizes, positions, behind/edge/overlap relationships, and spatial/emotional function; 7. the watercolor bloom, seep, diffusion, feathering, clear/soft edge variation, transparency, mixed overlap, and disappearance into warm paper; 8. the exact English word/phrase and optional note, with line-start/end/baseline/connector or gesture/contour/direction integration; 9. hard exclusions: no multi-photo layout, no altered or redrawn upper subject, no approximate split, no complete traced line drawing, no dense line detail, no decorative curves, no hard vector color blobs, no regular circles, no fixed pastel palette, no even color distribution, no rainbow, no digital gradient, no complex background, no cartoon, no commercial type, no template, no logo, and no watermark. Use concrete proposition, line action, field role, diffusion, transparency, color hierarchy, and text-line integration rather than relying on adjectives such as “premium,” “healing,” “romantic,” or “flowing.” ## Inspect and correct Review every result at full size and thumbnail size. Verify the exact split, truthful upper photography, recognizable distilled line subject, one core relation, active blank space, exactly two to four source-derived organic fields, varied diffused edges, meaningful transparent overlap, restrained color hierarchy, and English text behaving like another line. If it looks like a traced photo, remove most contour and retain only proposition-bearing lines. If color fields feel decorative, tie each to movement, negative space, or emotional weight—or delete it. If shapes look vector-perfect, restore seep, feathering, and uneven disappearance. If the palette feels generic, reselect hues from the source. If text looks pasted on, make a line physically initiate, support, cross, or extend it. Regenerate with one targeted correction when needed.
