Recolor white-hair assets & composite avatars

Avatar Creator Core

A Python library for recoloring white-hair assets and compositing avatar images using Pillow.

Features

• Recolor hair images to any RGB color while preserving shading.
• Composite hair and face images to create custom avatars.
• Simple API for loading, recoloring, and merging images.

Installation

pip install pillow

Or install from source:

pip install .

Usage

Example script (cli/main.py):

import os
import avatar_creator.core as core

hair_file = os.path.join("content/hair", "mid-length.png")
face_file = os.path.join("content/face", "face_1.png")

# Load images
face_img = core.load_rgba_image(face_file)
hair_img = core.load_rgba_image(hair_file)

# Recolor hair to orange
hair_img = core.recolor_to_rgb(hair_img, (255, 144, 25))

# Composite hair over face
avatar = core.merge_images(face_img, hair_img)

# Save result
avatar.save("output.png")

Example: Creating a blue-haired avatar

import os
import avatar_creator.core as core

face_img = core.load_rgba_image(
    os.path.join("content/face", "face_2.png")
)
hair_img = core.load_rgba_image(
    os.path.join("content/hair", "short.png")
)
hair_img = core.recolor_to_rgb(hair_img, (50, 100, 255))  # Blue
avatar = core.merge_images(face_img, hair_img)
avatar.save("avatar-blue.png")

Example: Batch generate avatars with different hair colors

import os
import avatar_creator.core as core

colors = [(255, 0, 0), (0, 255, 0), (0, 0, 255)]  # Red, Green, Blue
face_img = core.load_rgba_image(
    os.path.join("content/face", "face_1.png")
)
hair_img = core.load_rgba_image(
    os.path.join("content/hair", "mid-length.png")
)

for color in colors:
    recolored = core.recolor_to_rgb(hair_img, color)
    avatar = core.merge_images(face_img, recolored)
    avatar.save(f"avatar-{color[0]}-{color[1]}-{color[2]}.png")
