I’ve been generating a lot of watercolor style character illustrations lately, and there’s one specific look I keep coming back to. A single full-body figure, soft muted colors, hand-painted texture, and a plain paper background with tiny paint speckles floating around the character.
It looks like something out of a fashion sketchbook, and it works beautifully for Pinterest pins, blog graphics, and printable wall art.
The good news is that this style is very repeatable. Once I broke it down into a template, I could swap out the character, outfit, and props and get a consistent result every single time. In this post I’m sharing that exact template, plus 3 ready-to-use example prompts built from it.
How to Use the Template
Open ChatGPT, paste the template, and replace everything in square brackets with your own details. Keep the rest of the wording as it is, because those fixed phrases are what lock in the watercolor look.
You can also paste one of the example prompts below directly and just change small details like the outfit colors or the prop.
The Prompt Template
Here is the full template. Everything in [brackets] is a slot you fill in.
Create a delicate watercolor illustration of [subject: age, gender, hairstyle] [pose or action], shown in full body from [side profile / three-quarter view]. The subject wears [outfit: top, bottom, shoes] with [accessories or props]. Soft muted color palette of [2 to 3 colors], hand-painted watercolor texture with visible brush strokes and subtle ink linework. Plain textured watercolor paper background in warm off-white, with tiny scattered paint speckles floating around the figure. Soft light shadow beneath the feet, minimal ground detail like [faint cobblestones / simple shadow only]. Elegant storybook fashion illustration style, lots of negative space, no background scenery. Use aspect ratio 4:5.
Why Each Part Matters
A quick breakdown so you know which phrases you can change and which ones you should leave alone.
The subject, pose, outfit, and props are yours to play with. This is where each image gets its personality, so be specific. “A young woman walking” is fine, but “a young woman with a braided ponytail walking briskly with a coffee cup” gives you a much more interesting result.
The style phrases are doing the heavy lifting. “Hand-painted watercolor texture”, “textured watercolor paper background”, and “tiny scattered paint speckles” are what create the sketchbook feel. Keep them word for word.
The last line is the most important one. “Lots of negative space, no background scenery” stops ChatGPT from painting a full street scene behind your character. If it still adds a background, repeat this line at the end again.
And limit yourself to 2 or 3 muted colors. That restraint is what gives these illustrations their cohesive vintage look. The moment you list five colors, the image starts feeling busy.
1. Girl Walking with Coffee
The classic version of this style. Casual streetwear, side profile, and a coffee cup make it feel like a quiet morning moment.
Create a delicate watercolor illustration of a young woman with a low braided ponytail and oversized round glasses walking briskly, shown in full body from side profile. The subject wears a loose sage green t-shirt, baggy beige trousers cuffed at the ankle, and black canvas sneakers with a brown leather crossbody satchel and a takeaway coffee cup in hand. Soft muted color palette of sage, warm gray, and cream, hand-painted watercolor texture with visible brush strokes and subtle ink linework. Plain textured watercolor paper background in warm off-white, with tiny scattered paint speckles floating around the figure. Soft light shadow beneath the feet, minimal ground detail like faint cobblestones. Elegant storybook fashion illustration style, lots of negative space, no background scenery. Use aspect ratio 4:5.
2. Man with a Vintage Bicycle
The template works just as well for male characters. Linen and loafers keep the vintage feel, and one large prop like a bicycle changes the whole composition without breaking the style.
Create a delicate watercolor illustration of a young man with tousled dark hair leaning casually against a mint green vintage bicycle, shown in full body from three-quarter view. The subject wears a cream linen shirt with rolled sleeves, rust brown pleated trousers, and tan loafers, with a canvas tote bag hanging from the handlebar and a folded newspaper under one arm. Soft muted color palette of mint, rust, and ivory, hand-painted watercolor texture with visible brush strokes and subtle ink linework. Plain textured watercolor paper background in warm off-white, with tiny scattered paint speckles floating around the figure. Soft light shadow beneath the feet, minimal ground detail like simple shadow only. Elegant storybook fashion illustration style, lots of negative space, no background scenery. Use aspect ratio 4:5.
3. Grandmother with a Basket of Oranges
Older characters look wonderful in watercolor. The pearl details and cardigan give this one a gentle, nostalgic mood, and the tumbling orange adds a touch of motion.
Create a delicate watercolor illustration of an elderly woman with silver hair in a neat bun twirling gently mid-step, shown in full body from three-quarter view. The subject wears a dusty lavender midi dress under a white cardigan with pearl button details and soft gray Mary Jane shoes, holding a woven basket of oranges as one orange rolls out mid-air. Soft muted color palette of lavender, dove gray, and soft orange, hand-painted watercolor texture with visible brush strokes and subtle ink linework. Plain textured watercolor paper background in warm off-white, with tiny scattered paint speckles and small petals floating around the figure. Soft light shadow beneath the feet, minimal ground detail like scattered pebbles. Elegant storybook fashion illustration style, lots of negative space, no background scenery. Use aspect ratio 4:5.
A Few Extra Tips
If ChatGPT keeps painting full backgrounds, add “isolated character on plain paper, absolutely no scenery” at the end of your prompt. That usually fixes it.
For Pinterest, 4:5 and 2:3 both work well. For square social posts, just change the last line to “Use aspect ratio 1:1.”
And if you want a matching set of illustrations, keep the color palette and style lines identical across all your prompts and only change the character details. That’s how you get a series that looks like it came from the same artist’s sketchbook.
That’s the whole system. One template, endless characters. If you create something nice with it, I’d genuinely love to see it.
