Color map library for scientific visualizations. This library is a .NET port of tinycolormap.
| Name | Sample |
|---|---|
| Parula |  |
| Heat |  |
| Hot |  |
| Jet |  |
| Gray |  |
| HSV |  |
Reference: https://www.mathworks.com/help/matlab/ref/colormap.html
The HSV colormap is cyclic and is particularly useful for plotting angles or phases because the color transition from 1 to 0 is smooth. A phase wrap would thus not appear as a sharp edge.
| Name | Sample |
|---|---|
| Magma |  |
| Inferno |  |
| Plasma |  |
| Viridis |  |
| Cividis |  |
These colormaps are designed to be perceptually uniform (even in black-and-white printing) and friendly to colorblindness. Cividis is specially designed such that it enables as identical interpretation to both those without a CVD and those with red-green colorblindness as possible.
Magma, Inferno, Plasma, Viridis are released under CC0 by Nathaniel J. Smith, Stefan van der Walt, and (in the case of Viridis) Eric Firing: https://github.com/BIDS/colormap/blob/master/colormaps.py. Their python code is adapted for the use in C#.
Cividis is released under CC0 by the authors of PLOS ONE paper (Jamie R. Nuñez, Christopher R. Anderton, Ryan S. Renslow): https://doi.org/10.1371/journal.pone.0199239. We incorporated the LUT into C#.
| Name | Sample |

| Github |  |
This colormap is designed to mimic the color scheme used in GitHub contributions visualization.

| Turbo |  |
Turbo is developed as an alternative to the Jet colormap by Anton Mikhailov (Google LLC). See the blog post for the details. The original lookup table is released under the Apache 2.0 license. We merged it and re-licensed the part under the MIT license for consistency.

| Cubehelix |  |
Cubehelix is developed by Dr. Dave Green and is designed for astronomical intensity images. It shows a continuous increase in perceived intensity when shown in color or greyscale. This implementation uses Green's "default" scheme (start: 0.5, rotations: -1.5, hue: 1.0, gamma: 1.0). See the original publication for details.
The core function of this library is
var color = Color.GetColor(double x, ColormapType type);where x should be between 0.0 and 1.0 (otherwise, it will be cropped), and type is the target colormap type like Viridis (default) and Heat.
tinycolormap is also capable of producing quantized colormaps (i.e. the ones that have visible boundaries between colors) based on the user specified number of levels. Below is the example of the quantized Parula colormap using 10 quantization levels:
| Name | Sample |
|---|---|
| Parula |  |
Note that the supported range for number of levels is [1, 255].
To create a colormap quantization use:
var color = Color.GetColor(double x, uint quantization, ColormapType type);
