Future Request: NCL Color Palettes

[Breeze-Hu]

Hello!
Thank you very much for this package you have developed, which conveniently provides adjustments to colors in R.
There is a very classic set of color swatches in earth sciences: the color palette provided by NCL NCL color table, it seems that there is no similar palette provided by cols4all at the moment.
This GitHub project Rcolors provides some work that will hopefully help.

I wonder if you have considered adding this color palette to the package? I'd be very grateful if the addition is done!

Best wishes,
Hu

Thx for this request @Breeze-Hu .

Could you make this a bit more concrete? Which palette exactly (or series) are you referring to exactly? I mean, 270 palettes from rcolors is too much, and has overlap with other series.

What are the (original) sources of those palettes?

If there is one dominating source, we can call the (candidate) series that. Or, we could add a series named 'earth' to contain palettes from earth sciences. Note that in the latter case, there is overlap, e.g. matplotlib.terrain.

Thank you for your response. To be honest, I also find it difficult to distinguish which colors might overlap with the existing palette (though I do believe there are quite a few overlaps).

It seems that NCL might have organized a series of colors, which were later widely adopted in the research community, especially in the field of Earth sciences. I understand that this kind of effort can be quite substantial, and avoiding redundancy may be challenging. It might be reasonable to put this issue on hold or even close it altogether.

Thank you again for your time and consideration!
