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
.

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.
lcars_custom_pal <- lcars_colors_pal(c("pale-canary", "eggplant"))

p <- ggplot(diamonds, aes(carat, stat(count), fill = cut)) +
geom_density(position = "fill")
p + scale_fill_lcars2("pale-canary", "danub")
# p + scale_fill_manual(values = lcars_custom_pal(8)) # equivalent
p + scale_fill_lcars2("pale-canary", "danub", divergent = TRUE)
