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.

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.
