How to Create a Named Color in Matplotlib for Easy Use

If you're a data visualization enthusiast using Python's Matplotlib, you might often find yourself repeating color codes for your preferred shades in various plots. Using specific colors consistently can enhance the clarity and aesthetics of your charts. What if you could create named colors that you can refer to easily, rather than remembering hex values? In this post, we will walk through how to register new named colors in Matplotlib — allowing you to use them in a much simpler way.

The Problem: Why Named Colors?

When creating visualizations, color plays a critical role in conveying information. If you have favorite colors that you use frequently, it can be cumbersome to always type out the hex code. You want something like this:

Instead of having to write out the full hex code each time, having a named color would expedite your coding and make it more readable.

The Solution: Register New Named Colors

To achieve the creation of named colors in Matplotlib, you'll need to delve a bit into the library's internals. Though it may not be the prettiest solution, it does work efficiently.

Step 1: Import Required Modules

First, ensure you have Matplotlib installed and then import the necessary module as follows:
