r - 如何生成对色盲友好的 30 种不同颜色？

Question

我知道一些 R 包如 randomcolorR和 pals可以生成多种不同的颜色，但我不知道它们是否适合色盲？
有没有更好的方法来获得约 30 种不同的颜色，这些颜色也是色盲友好的？或者是否有任何表格/网络我可以搜索色盲友好的颜色？这样我就可以手动选择了。
先感谢您。

Answer 1

请注意 some sources recommend not using more than 8 colors in a colorblind-friendly palette

Also, it is recommended to use no more than 8 different colors.

任何状况之下:
Here是 8 个色盲友好颜色的 2 个(类似)调色板

# The palette with grey:
cbPalette <- c("#999999", "#E69F00", "#56B4E9", "#009E73", "#F0E442", "#0072B2", "#D55E00", "#CC79A7")

# The palette with black:
cbbPalette <- c("#000000", "#E69F00", "#56B4E9", "#009E73", "#F0E442", "#0072B2", "#D55E00", "#CC79A7")

和 here是一个包含 15 种色盲友好颜色的调色板

pal <- c("#000000","#004949","#009292","#ff6db6","#ffb6db",
 "#490092","#006ddb","#b66dff","#6db6ff","#b6dbff",
 "#920000","#924900","#db6d00","#24ff24","#ffff6d")
