Hello everyone! Are you enjoying the world of AI image generation? ✨
"I want to try drawing with AI, but it ends up looking too realistic like a photo, or conversely, it looks too much like CG, and it doesn't turn out the way I imagined..."
I'm sure many of you have that concern, right?
"I want to draw pictures with a gentler, fluffier atmosphere."
"I wish I could create soft art that I'd want to decorate my room with..."
The magic keyword I want you to try when you feel that way is the one I'm introducing today:
"Pastel"! 🎨
Just by adding this one word, your prompt will change as if by magic.
Today, let's take a look at the charm of "Pastel" together!
What kind of keyword is "Pastel"? 🎨
When you hear "Pastel," what kind of colors come to mind? 🌸
Many of you probably imagine soft and gentle shades, like the pale pink of spring cherry blossoms or refreshing mint green.
When you use this keyword in an AI image generation prompt, it mainly casts two spells! ✨
1. The color scheme becomes "fluffy" and gentle
When you enter a normal prompt, you sometimes get images where the colors are "too dark..." or "too sharp and hard on the eyes."
Just by adding "Pastel style" or "Pastel colors", the saturation of the entire screen is softly suppressed, and it is unified into a gentle tone like a marshmallow.
2. A "warmth" is born in the texture
Pastel painting is art created using chalk-like materials.
Therefore, a hand-drawn, grainy texture and soft expressions with blurred boundaries are added to the images generated by the AI.
It's perfect for when you want to erase that "this was clearly made by AI" digital feel and bring out an analog-style warmth 🎨
For example, just by adding 'Pastel' to a prompt like 'a cat playing in the garden,' you can create a single image that looks like a page from a picture book, with an outstanding healing effect.
No difficult settings are needed. Simply adding the word 'Pastel' can add 'gentleness' to your work. This is the greatest charm of this keyword! 💖

✨ Copilot [GPT Image 1.5]
📖 First image: Reference image

🎨 Second image: Art style = Pastel

Overall atmosphere: Copilot
The first image is a sharp anime style, but the second has a soft, gentle, dream-like atmosphere ✨
Just by adding 'Pastel,' the fantastical beauty stands out much more than realism 🎨
It has shifted from crisp vividness to a soft worldview where everything is wrapped in magic.
Differences in character expression: Copilot
The girl's expression has also become softer, and the skin texture and hair are drawn with a fluffy touch 💕
The first image has a digital-like clarity, while the second is characterized by a hand-drawn warmth 👗
Because the outlines are slightly blurred, the character appears to blend gently into the background.
Differences in background: Copilot
The blue sky has changed to a pale gradient like a sunset, and the mountains and tents have also taken on a picture-book touch 🏔️
The color palette of the sky has shifted to pinks and oranges, evolving into a romantic impression overall ✨
Rather than the quiet of a campsite at night, a calm and warm atmosphere is clearly expressed.
Other features: Copilot
An interesting point is that the light is softly diffused throughout, and the boundaries of the shadows are blurred 💡
It's the unique fun of AI that the worldview can change this much with the same prompt just by changing the technique 📸
When you think, 'I want to make this gentler,' the word 'pastel' becomes the ultimate spice.
✨ Gemini 【 NanoBananaPro 】
📖 1st image: Reference image

🎨 2nd image: Art style = Pastel

Overall atmosphere: Gemini
The first image is a vivid, realistic anime-style starry sky, while the second has a gentle, soft atmosphere like a picture book ✨
By using the word 'pastel,' the digital feel is reduced, resulting in a warm, hand-drawn style of art 🎨
The crisp atmosphere has been replaced by a 'dreamy' world where the air feels soft and hazy.
Differences in character expression: Gemini
The first image features authentic mountaineering gear, but the second shows her in a dress and cardigan, giving a more refined impression 👗
Her expression has also become soft and gentle, perfectly capturing the 'fragile and kind' feeling unique to pastels 💕
The way the boundaries between the background and the character are slightly blurred makes it lovely how the girl blends into the scenery.
Differences in background: Gemini
The first image is a starry sky you could get lost in, but the second has evolved into an artistic night sky with swirling brushstrokes 🌌
The light from the campfire has also changed from a strong glare to a 'slow, warm glow,' doubling the healing effect of the camping scene 🔥
The depiction of the trees is not overly detailed; by intentionally softening their shapes, it evokes a sense of nostalgia, like a scene from a memory.
Other features: Gemini
Overall, the color boundaries are blurred, creating a texture that conveys the feel of canvas or paper 📸
It's fascinating how generative AI can completely change the genre of a work just by adding a single word 💡
Once you master 'art styles' in your prompts, you'll be able to freely create worlds exactly as you imagine them.
Bonus
Difference from 'Light/Color = Pastel Colors'

Pastel colors (color specification)
This is a specification to make the colors of the character and background 'pale and bright' 🍭
It keeps the crisp texture of anime coloring while making the colors themselves gentle.
Use this when you want to create a fresh and pop-style screen!
Art style = Pastel (specifying the technique)
Specify a "coloring style" that looks like it was drawn with chalk 🎨
It is characterized by the texture of paper grain and the soft blending of colors.
It is perfect for when you want to bring out the warmth of hand-drawing or an emotional atmosphere.
How to use them differently?
If you want to make "just the colors" cute, specify pastel colors! 💡
If you want to make the "overall atmosphere of the picture" gentle, choose an art style.
Mixing both allows you to create a super fluffy and cute worldview 🚀

📝 Summary
The interesting thing about AI image generation is that the worldview changes like magic with just a single word.
This time, just by adding "pastel," the digital picture changed into a gentle atmosphere like a hand-drawn one ✨
Being able to shape your own "ideal atmosphere" with just one word choice is a major appeal of AI 💕
Let's play by intuitively adding words like "I want to make it softer" or "I want to make it more powerful."
Everyone, please enjoy your creative activities with AI to the fullest with free ideas! 🚀
🔜 Next Preview
Did the charm of "pastel" come across? ✨
When you want to create a fluffy and gentle worldview, please be sure to add this word to the corner of your prompt.
Now, the keyword I will introduce next time is "Acrylic", which has a completely different atmosphere even though it is the same art style! 🎨
In contrast to the "fluffiness" of pastel, it is characterized by vivid, crisp coloring and a powerful texture that makes you feel the impasto of the paint.
This is a must-see for those who want to draw more energetic and impactful illustrations!
Look forward to next time!
Let's expand the range of expression together! 👋
Digisashimi's musings
I generated them a few times, and it was interesting to see that Copilot tends to imagine daytime, while Gemini tends to imagine nighttime.
I was playing around by making illustrations of Shion.
I'll be showing them off little by little 🥰
