Changes in version 2.0-1                        

  - Added pointers to the colorspace package and base R in a new startup
    message. The colorspace package provides better functions for
    simulating color vision deficiency: simulate_cvd(), deutan(),
    protan(), tritan(). More modern robust color palettes are available
    in hcl.colors() and palette.colors() in base R as well as further
    tools in colorspace. References providing more details:
