The trekcolors
package provides a collection of color palettes based
on Star Trek. It also offers functions for custom palettes and scale_*
functions for use with ggplot2
.
Install the CRAN release of trekcolors
with
install.packages("trekcolors")
Install the development version from GitHub with
# install.packages("remotes")
remotes::install_github("leonawicz/trekcolors")
library(trekcolors)

The four LCARS palettes that have a year in their series name are special in that these official standard LCARS colors have formal names.

In addition to these and all the other predefined palettes, custom
palettes can be constructed using official LCARS color names. This is
like colorRampPalette
but with the ability to recognize official LCARS
color names. This functionality was leveraged by scale_color_lcars1
and scale_color_lcars2
seen above when making sequential or divergent
palettes based on specific LCARS colors for use with ggplot.
