AI Coloring Page

AI Coloring Page Generator

Generate printable coloring pages and line art illustrations using each::sense — the intelligent AI agent that automatically selects the best model for your request.

Quick Start

Requires an each::labs API key. Get one at eachlabs.ai.

Using curl

curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "messages": [
      {
        "role": "user",
        "content": "Generate a coloring page: a friendly dragon sitting in a garden surrounded by flowers and butterflies. Black and white line art, clean outlines, no shading or filled areas, suitable for children ages 5-8 to color in. White background."
      }
    ],
    "stream": false
  }'

Using Python (OpenAI SDK)

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_EACHLABS_API_KEY",
    base_url="https://eachsense-agent.core.eachlabs.run/v1"
)

response = client.chat.completions.create(
    model="eachsense/beta",
    messages=[{
        "role": "user",
        "content": "Generate a coloring page: a friendly dragon sitting in a garden surrounded by flowers and butterflies. Black and white line art, clean outlines, no shading or filled areas, suitable for children ages 5-8 to color in. White background."
    }]
)

print(response.choices[0].message.content)

From Reference Image

Convert a photo or artwork into a coloring page:

curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "messages": [
      {
        "role": "user",
        "content": [
              {"type": "text", "text": "Convert this image into a coloring page. Extract the main outlines and shapes, remove all color and shading, create clean black line art on a white background suitable for coloring with crayons or colored pencils."},
              {"type": "image_url", "image_url": {"url": "https://example.com/colorful-scene.jpg"}}
            ]
          }
    ],
    "stream": false
  }'

Images are sent inside messages using the OpenAI multimodal content format. Maximum 4 images per request.

Streaming

Set "stream": true for real-time Server-Sent Events (SSE) responses, or "stream": false to receive the complete result in a single response. Streaming is useful for showing progress in UIs; non-streaming is simpler for scripts and automation.

Coloring Book Series

THEMES=(
  "Coloring page: an underwater coral reef scene with tropical fish, a sea turtle, an octopus, and seaweed"
  "Coloring page: a medieval castle with a knight on horseback, a drawbridge, and flags on turrets"
  "Coloring page: a space station orbiting Earth with an astronaut floating outside, stars, and a shuttle approaching"
  "Coloring page: a dense jungle scene with a toucan, a monkey, a tree frog, vines, and large tropical leaves"

  curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \

    -H "X-API-Key: $EACHLABS_API_KEY" \
    -d "{

Prompt Tips

• Always specify "black and white line art" — without this, the model may add color or shading
• Say "no shading, no filled areas, no gray tones" to get clean colorable outlines
• Mention the age group to calibrate complexity
• White background ensures clean printing
• "Clean outlines" prevents sketchy or fuzzy lines
• Avoid "realistic" — coloring pages work best with stylized or cartoon-like art

Print Specifications

• Best printed at standard paper sizes (Letter 8.5x11", A4)
• Request images with generous margins for easy coloring at the edges
• Thick outlines (specify "bold outlines") are easier for young children
• Fine outlines work better for adult coloring with colored pencils
