Questions tagged [viridis]
An R package implementing several popular color maps, such as the 'viridis' (the default) 'magma', 'plasma', 'inferno', and 'cividis' in R. These color maps are designed to be perfectly perceptually-uniform, both in regular form and also when converted to black-and-white. They are also designed to be perceived by readers with the most common form of color blindness (all color maps in this package) and color vision deficiency ('cividis' only).
