16 Answers Sorted by: 92 A neat way to generate RGB triplets within the 256 (aka 8-byte) range is color = list (np.random.choice (range (256), size=3)) color is now a list of size 3 with values in the range 0-255. You can save it in a list to record if the color has been generated before or no. Share Improve this answer Follow

We can generate color using python libraries such as Numpy, Matplotlib, and turtle. RGB represents Red, Green, and Blue. It has an integer value from 0 to 255. The combination of these three colors gives many colors. The hexadecimal format starts with the #sign, followed by six hexadecimal digits. The hexadecimal colors are Red, Green, and Blue.

Matplotlib has a number of built-in colormaps accessible via matplotlib.colormaps. There are also external libraries that have many extra colormaps, which can be viewed in the Third-party colormaps section of the Matplotlib documentation. Here we briefly discuss how to choose between the many options.

The solution is to stop trying to assign a different color to each marker on a single line, but instead to make a scatter plot which is what this really is!
