Named Colormaps

Named colormaps supported by LookupTable, Plotter, and other plotting-related methods.

The colormaps on this page are from multiple packages:

• mpl - matplotlib colormaps.

• cc - colorcet continuous and categorical colormaps.

• cmo - cmocean colormaps.

• cmc - cmcrameri colormaps.

The type of the colormap is indicated as:

• LSC if it is a LinearSegmentedColormap

• LC if it is a ListedColormap

Each colormap is also tagged as:

• - if it is perceptually uniform

• - if it is not perceptually uniform

A colormap is considered perceptually uniform if its color gradients are evenly spaced, meaning equal steps in data produce equal perceptual changes.

Some colormap libraries assess perceptual uniformity using only the lightness component (\(L^*\) in the Lab color space), while others also consider chromatic components (\(a^*\) and \(b^*\)). For the colormaps on this reference page, both lightness and color differences must meet the uniformity criteria to earn the label.

Specifically, a colormap is labeled as perceptually uniform if:

1. The cumulative change in lightness (\(L^*\) from CAM02-UCS) progresses linearly. See lightness of matplotlib colormaps.

2. The cumulative color difference (\(\Delta E\), using the CIEDE2000 metric) progresses linearly. See Fig. 3c: cumulative color lightness difference.

Linearity is defined as having a coefficient of determination (\(R^2\)) greater than 0.99 when fitted with linear regression. When choosing a colormap, those with the tag should be preferred over those with the tag.

警告

Many of the matplotlib colormaps such as jet are not perceptually uniform and should be avoided where possible, since these colormaps can generate misleading visualizations. Colormaps from colorcet and cmocean, and cmcrameri are therefore generally recommended over those from matplotlib. See the misuse of colour in science communication and testing perceptual uniformity for more information.

Refer to the flowchart in the following dropdown for guidance on how to choose a colormap.

注釈

Some colormap names such as gray and rainbow are duplicated across packages, but have slight variations in the mapped colors. Colormaps from colorcet have priority and are used first if available, followed by cmocean, followed by the stock colormaps from matplotlib.

注釈

Install PyVista with pyvista[colormaps] or pyvista[all] to also install the colorcet, cmocean, and cmcrameri packages.

CET Colormaps

This section includes all colorcet colormaps that have a named CET alias (originally from the Center for Exploration Targeting).

Colormap names have the form:

CET_[prefix]{type}{number}[suffix]

Where the prefix and suffix are optional ([]) and the type and number are required ({}).

Prefix :

Indicates additional information about color perception.

• CB: Colorblind—safe for red—green color vision deficiency (protanopia/deuteranopia)

• CBT: Colorblind—safe for blue—yellow color vision deficiency (tritanopia)

Type :

The type of colormap.

• C: Cyclic

• D: Diverging

• L: Linear

• R: Rainbow

• I: Isoluminant

Number :

A version number (starting at 1) for each unique [prefix]{type} combination.

Suffix :

Indicates a minor variation of the base colormap.

• A: Alternate version (such as adjusted contrast or hue emphasis)

• s: Shifted version (phase-shifted)

注釈

Most of the colorcet colormaps presented above in Named Colors are duplicated here (using their CET aliases).

Linear (Sequential)

Colormaps that progress in a single direction, ideal for representing ordered data such as intensities or magnitudes.
