Viridis Color Palettes

Viridis

The viridis package provides eight eye-catching color palettes to use in data visualizations:

• magma
• inferno
• plasma
• viridis
• cividis
• rocket
• mako
• turbo

Optimized for perception

According to the virids documentation, the palettes:

are designed to improve graph readability for readers with common forms of color blindness and/or color vision deficiency. The color maps are also perceptually-uniform, both in regular form and also when converted to black-and-white for printing.

Viridis in action

Each plot uses a different viridis color palette to visualize the median high temperature (F) by US county.

Usage

To use a viridis palette in your plot, include scale_*_viridis() in your ggplot2 call:

mpg |>  
  ggplot(aes(x = displ, y = cty, color = hwy)) +
    geom_point() +
    scale_color_viridis(option = "A")
