The project is in a healthy, maintained state
This library is called colours. It unifies colour-related constants and methods, including R,G,B values for colours and the commonly known "HTML colours", such as "slateblue" or "royalblue" and so on. The primary use case for this project is to make commandline-scripts display text on the terminal with colours. For more information about this project, have a look at the online documentation for this gem at the link called "documentation", at the bottom right side of the colours gem homepage:
