Blind color figures

[laiaju...@gmail.com]

  Hi everyone, I'm about to start the publication process and wanted to ask if anyone might be able to help me with a code that is color-blind friendly but also allows me to keep the same regions in the same color across all figures. 

Thanks in advance!

Hi Laia,

 

Yes, it’s super important to stick with the same colours for each population across all the plots so the reader doesn’t get confused.

 

Here are a few colour-blind friendly options you might find handy:

 

library(dartRverse)

t1 <- bandicoot.gl

pcoa <- gl.pcoa(t1)

 

# Option 1: Adobe Color Wheel (great, but limited to 5 colours)

# https://color.adobe.com/create/color-accessibility

# Just click the middle of a colour to get the code

pop_colors <- c("#0A09EB", "#EAE5A6", "#42CAEA", "#DAEB09", "#6B3896")

gl.pcoa.plot(pcoa, x = t1, pt.colors = pop_colors)

 

# Option 2: Okabe-Ito palette (one of the best for accessibility!)

# Info: https://siegal.bio.nyu.edu/color-palette/

library(pals)

pop_colors <- okabe(n = nPop(t1))

gl.pcoa.plot(pcoa, x = t1, pt.colors = pop_colors)

 

# Option 3: RColorBrewer palettes

library(RColorBrewer)

display.brewer.all(colorblindFriendly = TRUE)

pop_colors <- brewer.pal(n = nPop(t1), name = "Dark2")

gl.pcoa.plot(pcoa, x = t1, pt.colors = pop_colors)

 

Cheers,

Luis
