Color palette for a heavy overshirt: brown and mint green

Reference order: image 1 is the portrait reference, image 2 is the palette, and image 3 is the clothing and footwear reference.

Use case: identity-preserve, three-reference virtual outfit try-on and color-palette compositing.
Create ONE NEW realistic full-body fashion portrait, exact intended output 1024 x 1536 pixels, portrait 2:3. Production ID P0450 is metadata only and must not appear in the image.
THREE REAL REFERENCES: Image 1 is Marilyn Monroe identity reference (M16_ORANGE_KNIT_AI); preserve her recognizable face, facial proportions, age, natural expression, blonde hairstyle and natural skin. Image 3 is the EXISTING exact garment-and-shoe reference (F062); dress her in ALL those garments and its one complete pair of shoes. Image 2 is the authoritative four-band palette, source order #B6CBBD, #754E1A, #CBA35C, #F8E1B7.
Do not keep the original outfit or background from Image 1. This is a newly imagined full-body fashion composition, not a restoration or recreation of the historic photo. Keep source files untouched. Preserve the identity, not source framing. For a bust or seated identity reference, construct a believable proportional full standing figure. Do not copy source photo captions, watermarks, signatures or image borders into this NEW composition. Do not copy identity-source hat, gloves, jewelry or other costume accessories unless the garment reference includes them.
Outfit: Heavy overshirt with cargo pants. Preserve the actual design shown in Image 3: exact garment count, style, neckline, sleeve length, coat/skirt/trouser lengths, collar, cuffs, closures, waistband, pleats, existing pattern geometry, fabric texture, footwear shape, toe, straps, heel and sole. Adapt these existing items naturally onto the body, not flat-lay. No replacement designs or extra accessories. Opaque tasteful clothing.
Apply region colors as follows: outer (mid-short heavy cotton twill shirt-jacket, two chest pockets, buttoned cuffs, front naturally open and flat): #754E1A (clothing_primary); inner (crewneck jersey long-sleeve T-shirt): #F8E1B7 (background); lower (straight-leg cotton cargo trousers, flat side patch pockets): #CBA35C (secondary); shoes (one pair of unbranded low-top leather sneakers, left and right shoes completely and independently displayed, uppers, sole edges, and all laces or buckles clearly visible): #B6CBBD (accent). Whole main garment must visibly carry #754E1A, with realistic highlights and shadows. Environment main supporting color #F8E1B7, small supporting surfaces/details #CBA35C and #B6CBBD. Clothes are visually primary; environment secondary. Palette colors guide material colors, not every pixel. Keep natural skin, blonde hair, eyes and neutral physical light/shadow; no global color cast.
Season is autumn, chosen as an artistic suitability recommendation. Scene: a restrained autumn city walkway, a few distant autumn leaves, soft warm daylight. Pose: natural relaxed standing with one foot slightly forward, arms relaxed. Eye-level fashion photography, naturally graceful and anatomically plausible. Entire head/hair and BOTH full shoes visible with breathing room. Face and important garment detail sharp, backdrop restrained and slightly defocused. No dramatic skirt lifting.
Output one cohesive photoreal human wearing the entire outfit. NO flat lay, mannequin, product board, collage, split screen, extra people, duplicate limbs or duplicate garments. NO written text, letters, numbers, logos, watermarks, captions, color swatches, color card, HEX labels, footer or border. Do not draw the input palette card.
Quality priority: Both feet separated sideways with no crossing or overlap. Full-length cargo trousers retain original length with hems resting at shoe tops; both full low leather sneakers visible, blank unbranded tongues. Face, ears, neck, exposed chest and hands must have coherent natural skin coloration; no garment or palette color bleeding onto skin, natural neutral shadows only.
