Understanding Matplotlib Color Basics

Matplotlib Color provides a wide range of options for specifying colors in your plots. The most common methods include using color names, RGB values, and hexadecimal codes. Let’s explore these basic color specifications with some examples.

Using Color Names

Matplotlib supports a variety of predefined color names that you can use to specify colors in your plots. Here’s a simple example:

import matplotlib.pyplot as plt

plt.figure(figsize=(8, 6))
plt.plot([1, 2, 3, 4], [1, 4, 2, 3], color='red', label='Red Line')
plt.plot([1, 2, 3, 4], [2, 3, 4, 1], color='blue', label='Blue Line')
plt.title('Matplotlib Color Example - how2matplotlib.com')
plt.xlabel('X-axis')
plt.ylabel('Y-axis')
plt.legend()
plt.show()

Output:

Matplotlib Color: A Comprehensive Guide to Customizing Your Plots

In this example, we create two line plots using the color names ‘red’ and ‘blue’. Matplotlib Color recognizes a wide range of color names, making it easy to specify colors without needing to remember specific color codes.

Using RGB Values

For more precise color control, you can use RGB (Red, Green, Blue) values to specify colors in Matplotlib. RGB values range from 0 to 1 for each color component. Here’s an example:

import matplotlib.pyplot as plt

plt.figure(figsize=(8, 6))
plt.plot([1, 2, 3, 4], [1, 4, 2, 3], color=(0.8, 0.2, 0.1), label='Custom Red')
plt.plot([1, 2, 3, 4], [2, 3, 4, 1], color=(0.1, 0.5, 0.9), label='Custom Blue')
plt.title('Matplotlib Color with RGB Values - how2matplotlib.com')
plt.xlabel('X-axis')
plt.ylabel('Y-axis')
plt.legend()
plt.show()

Output:

In this example, we use RGB tuples to specify custom shades of red and blue. The RGB values allow for fine-tuned color selection, giving you more control over the exact hues in your plots.
