prismatic (development version)

prismatic 1.1.2

color() now maintains the names of the input vector, allowing plot() to use the color names rather than the hex values when label = TRUE. You can also provide label with a custom set of color labels. Unnamed colors are labelled with their hex values (@gadenbuie, #27).
Printing color objects is now powered by {cli}, which has superseded {crayon} (jack-davison, #28).
