Color Notebook

ColorAide's documentation is rendered with Python Markdown and Pymdown Extensions. The color notebook implements a dynamic, live environment allowing for on the fly page rendering and interactive Python code examples with beautiful visualization of color. This is accomplished by using Pyodide to execute the required Python modules to render the desired pages.

Though Pyodide is used to run the Python code, the actual code is handled special so that we can intercept color objects at various times and translate them to color swatches and gradients. Because of this, asynchrounous code is not really handled
