A header-only, single-file library for colormaps written in C++11.

These colormaps are designed to be perceptually uniform (even in black-and-white printing) and friendly to colorblindness.
The original colormaps 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++11.

This colormap is designed to mimic the color scheme used in GitHub contributions visualization.
tinycolormap does not have any dependencies except for C++11 standard library.
tinycolormap is a header-only library, so you do not need to compile it. You can use it by
- Adding the path to the cloned tinycolormap repository to your project's include paths, or
- Copying the file
tinycolormap.hppto your project (note that tinycolormap consists of only that single file).
If your project is managed by Cmake https://cmake.org/, then the ExternalProject_Add is useful as tinycolormap provides CMakeLists.txt for this purpose.
This repository includes the following optional tools:
- PNG Exporter: This tool exports all the available colormaps as PNG images.
The optional tools are managed by CMake https://cmake.org/. They can be built by, for example,
mkdir build
cd build
cmake [PATH_TO_TINYCOLORMAP] -DTINYCOLORMAP_BUILD_TOOLS=ON
make
Tips: if CMake could not find Qt5, it needs to specify the path to Qt5 explicitly by adding an option: -DCMAKE_PREFIX_PATH=[PATH_TO_Qt5].
#include <iostream>
#include <tinycolormap.hpp>
int main()
{
// Define a target value. This value should be in [0, 1]; otherwise, it will be cropped to 0 or 1.
const double val
602A
ue = 0.5;
// Get the color as a 3-dimensional double-valued vector. Here, Viridis is specified as a colormap.
const tinycolormap::Color color = tinycolormap::GetColor(value, tinycolormap::ColormapType::Viridis);
// Print the RGB values. Each value is in [0, 1].
std::cout << "r = " << color.r() << ", g = " << color.g() << ", b = " << color.b() << std::endl;
return 0;
