This project provides two simple Python scripts to generate colorful gradient images either linear or radial using NumPy and Pillow (PIL).

• ✅ Generate linear gradients (vertical or horizontal)
• ✅ Generate radial gradients (with adjustable radius)
• ✅ Fully interactive: you can enter parameters like orientation or radius
• ✅ Automatically saves generated images to an images/ folder next to the script

Make sure you have Python 3.8+ installed. Then, install dependencies:

pip install numpy pillow

The linear gradient script creates an image that transitions smoothly from a start color to an end color, either vertically or horizontally.

python generate_linear_gradient.py

Enter the orientation of the gradient (horizontal/vertical) :  horizontal

The generated image will be saved as:

/images/linear_gradient.png

• Image size: 500 x 300
• Start color: Red (255, 0, 0)
• End color: Blue (0, 0, 255)
• Default orientation: Vertical

The radial gradient script generates a gradient that spreads outward from the center of the image, fading from a start color to an end color. You can control how fast the gradient spreads using the radius.

python generate_radial_gradient.py

Please enter the radius for the radial gradient(0-1) : 0.5

The generated image will be saved as:

/images/radial_gradient.png

• Image size: 500 x 500
• Start color: Yellow (255, 255, 0)
• End color: Black (0, 0, 0)
• Default radius: 250

Both scripts create an images/ folder automatically if it doesn’t exist and store the generated images inside.

• You can freely modify the width, height, colors, and radius in each script.
• Perfect for generating backgrounds, art assets, or UI design placeholders.
