jiho / chroma Goto Github PK

Hi

You might already know it, but just in case: I tried the dev version, and now face some errors...

Thanks!!

Hi

Thanks for this nice package! I was looking at the post on chroma.js(), where they talk a lot about the lighntess correction, showing for example this piece of code:

chroma.scale(['white', 'yellow', 'red', 'black'])
   .correctLightness();

Is this function also available in the R package?

Thanks!

While this would be useful to color match the theme in latex presentations, those palettes are not for graphical representation of continuous variables and maybe only valid for a small number of categorical levels. Even then, there is no argument for their perceptual value.

To be considered together with adding support for other palettes.

Might be problematic with range()
