Create color gradients based on list-like input data

Gradpyent, a Python Gradient Generator

Gradpyent is a Python package for generating color gradients based on list-like inputs and start/end color values. The generated gradients are ideal for data visualization, user interfaces, or anywhere you want to convert a list of values into a color gradient.

This package allows you to specify colors in a variety of formats including RGB, HTML, and KML, giving you the flexibility to match your specific needs.

The gradient generation algorithm automatically scales input values outside the range of 0-1, ensuring the generated gradient remains consistent and visually pleasing.

Installation

You can install Gradpyent directly from PyPI:

pip install gradpyent

Usage

Basic usage:

from gradpyent.gradient import Gradient

# Define the start and end colors as RGB, HTML, or KML
start_color = 'rgb(255,0,0)'  # Red in RGB
end_color = '#0000ff'  # Blue in HTML

# Instantiate the gradient generator, opacity is optional (only used for KML)
gg = Gradient(gradient_start=start_color, gradient_end=end_color, opacity=1.0)

# Define the input list
input_list = [0, 0.5, 1]

# Generate the gradient
gradient = gg.get_gradient_series(series=input_list, fmt='html')

print(gradient)

Examples

Here are some more examples demonstrating how to use different color formats and list inputs:

• RGB colors:

start_color = 'rgb(255,0,0)'  # Red
end_color = 'rgb(0,0,255)'  # Blue
input_list = [0, 0.5, 1]

• HTML colors:

start_color = '#ff0000'  # Red
end_color = '#0000ff'  # Blue
input_list = [0, 0.5, 1]

• KML colors:

start_color = 'ff0000ff'  # Red
end_color = 'ffff0000'  # Blue
input_list = [0, 0.5, 1]

• Scaling input values:

start_color = 'rgb(255,0,0)'  # Red
end_color = '#0000ff'  # Blue
input_list = [-5, 0, 5, 10]  # Values outside 0-1 range
