Go to the end to download the full example code. Matplotlib has a number of built-in colormaps accessible via matplotlib. 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. For help on creating your own colormaps, see Creating Colormaps in Matplotlib. The idea behind choosing a good colormap is to find a good representation in 3D colorspace for your data set. The best colormap for any given data set depends on many things including:.

The Color tutorials and examples demonstrate how to set colors and colormaps. You may want to read those instead. This module includes functions and classes for color specification conversions, and for mapping numbers to colors in a 1-D array of colors called a colormap. Mapping data onto colors using a colormap typically involves two steps: a data array is first mapped onto the range using a subclass of Normalize , then this number is mapped to a color using a subclass of Colormap. Two subclasses of Colormap provided here: LinearSegmentedColormap , which uses piecewise-linear interpolation to define colormaps, and ListedColormap , which makes a colormap from a list of colors. Creating Colormaps in Matplotlib for examples of how to make colormaps and. Choosing Colormaps in Matplotlib for a list of built-in colormaps. Colormap normalization for more details about data normalization. More colormaps are available at palettable. Caching is used for efficiency. Colors that Matplotlib recognizes are listed at Specifying colors.

For example, 'blue' maps to ' FF' whereas 'xkcd:blue' maps to ' DF', matplotlib.colors. The Styling with matplotlib.colors section contains additional information about controlling colors and style properties, matplotlib.colors. This would make it impossible for a viewer to interpret the information in a plot once it is printed in grayscale.

In Python, we can plot graphs for visualization using the Matplotlib library. For integrating plots into applications, Matplotlib provides an API. This function is used to specify the color. It is a do-nothing function. We can use this function for various data visualizations and obtain insights from them.

Matplotlib is a powerful visualization package for Python. It is very customizable, thanks to this it is widly used in commercial and in academic use cases. In this article, I will show you 9 different ways how to set colors in Matplotlib plots. All parts of the plot can be customized with a new color. You can set colors for axes, labels, background, title. However, not every data scientist is a graphic designer that can compose nice looking colors in a single plot, so I can show you how to use predefined Matplotlib styles to get attractive plots. The numbers should be in range [0, 1].

In Python, Matplotlib has a list of default colors that it uses for the elements in a plot depending on the number of total elements. For example, we can use the following code to plot lines that show the first 10 default colors in Matplotlib:. Matplotlib chooses the first 10 default colors for the lines in the plot.
