In the digital world, colors are represented in different formats. RGB, Hexadecimal format are just some of the commonly used formats.

In this tutorial, we will learn how to generate random colors in Python. When we talk about generating random colors, we are going to generate a random code that can represent a color. Different methods will generate color codes in different formats.

Generate random colors in RGB format in Python

RGB stands for Red, Green, and Blue. Together, they represent the color spectrum in the digital world. Red, Green, and Blue together can represent every color, and each color is 8 bits. This means that they have integer values ​​from 0 to 255.

To generate a random color in RGB format, we will generate a list or tuple of random integers from 0 to 255.

The following code shows how to achieve this.

import numpy as np

color = list(np.random.choice(range(256), size=3))
print(color)

Output:

[245, 159, 34]

In the code above, we generate random integers using the random_integer_s NumPyfrom the module random. It simply generates a random integer between 0 and 255 three times and stores it in a list. Since random integers can be generated in many other ways, the main focus should be on the logic of the code.

Generate random colors in hexadecimal format in Python

In hexadecimal, colors are represented by six hexadecimal digits prefixed with a # sign. The format is #RRGGBB, where R, G, and B represent Red, Greenand Blue, respectively, and are hexadecimal numbers.

We can generate random colors in this format using the code shown below.

import random

color = ["#" + "".join([random.choice("0123456789ABCDEF") for j in range(6)])]
print(color)

Output:

['#BE3559']

In the above code, we select six random numbers from the specified hexadecimal number and then combine join()them with #the symbol using the function.

There are many other color formats available, and converting between them is very easy.

One thing to remember is that we generated color codes in different formats throughout this tutorial. To actually see these colors, we have to generate some graphics using other modules or draw some graphs.

For example, in the following code, we will use Matplotlibthe scatter plot module to plot simple points with the generated color codes.

import random
import matplotlib.pyplot as plt

color = ["#" + "".join([random.choice("0123456789ABCDEF") for j in range(6)])]
print(color)

plt.scatter(random.randint(0, 10), random.randint(0, 10), c=color, s=200)
plt.show()

Output:
