[Rd] New grDevices::hcl.colors()

[Abs Spurdle]

Hi Z

I think supporting HCL color spaces more, is a *very* good idea.
However, I doubt many R users, understand the motivation for HCL color
spaces.

I've reproduced Ross Ihaka's notes on color, on my personal website:
https://sites.google.com/site/spurdlea/exts/ihaka_r_stats_787_10_color.pdf

(This has been reproduced with permission).

Another good article is:
https://www.r-project.org/conferences/DSC-2003/Proceedings/Ihaka.pdf

And the colorspace package vignette is also a good resource:
https://cran.r-project.org/web/packages/colorspace/vignettes/hcl-colors.pdf

These are good resources for people interested in mathematical or
statistical graphics.
