## What is it?

Colorcet is a collection of
perceptually uniform colormaps for use with Python plotting programs like
[bokeh](http://bokeh.pydata.org),
[matplotlib](http://matplotlib.org),
[holoviews](http://holoviews.org), and
[datashader](https://github.com/bokeh/datashader) based on the
set of [perceptually uniform colormaps](https://arxiv.org/abs/1509.03700) created
by Peter Kovesi at the Center for Exploration Targeting.


## Installation

Colorcet supports Python 3.7 and greater on Linux, Windows, or Mac
and can be installed with conda:

```sh
conda install colorcet
```

or with pip:

```sh
python -m pip install colorcet
```

To work with JupyterLab you will also need the PyViz JupyterLab extension:

```sh
conda install -c conda-forge jupyterlab
jupyter labextension install @pyviz/jupyterlab_pyviz
```

Once you have installed JupyterLab and the extension launch it with:

```sh
jupyter-lab
```

If you want to try out the latest features between releases, you can get the latest dev release by installing:

```sh
conda install -c pyviz/label/dev colorcet
```

For more information take a look at [Getting Started](http://colorcet.holoviz.org/getting_started).

## Learning more

You can see all the details about the methods used to create these
colormaps in [Peter Kovesi's 2015 arXiv
paper](https://arxiv.org/pdf/1509.03700v1.pdf).  Other useful
background is available in a [1996 paper from
IBM](http://www.research.ibm.com/people/l/lloydt/color/color.HTM).

The Matplotlib project also has a number of relevant resources,
including an excellent
[2015 SciPy talk](https://www.youtube.com/watch?v=xAoljeRJ3lU), the
[viscm tool for creating maps like the four in mpl](https://github.com/matplotlib/viscm), the
[cmocean site](http://matplotlib.org/cmocean/) collecting a set of maps created by viscm,
and the [discussion of how the mpl maps were created](https://bids.github.io/colormap/).


## Samples

Some of the Colorcet colormaps that have short, memorable names (which are probably
the most useful ones) are visible here:

But the complete set of 100+ is shown in the [User Guide](http://colorcet.holoviz.org/user_guide).
