How do I colour jitter points to be different colours in a geom_boxjitter plot?

I'm trying to match the colours of the points from the jitter plot to the colours of the boxes. I can colour them one colour or the other, but I can't seem to set them to match the colour of the boxes.

Alternatively, I've figured out how to change the colours of the jitter points using geom_jitter but can't seem to figure out how to shift them to the side of the boxplot like the geom_boxjitter would have them. I thought maybe I could add "position = ..." to my geom_jitter() but that didn't seem to work...

                                outlier.colour = NULL, outlier.shape = 1,

                                errorbar.length = 0.2)+
  theme(panel.background = element_rect(fill = 'white', colour = 'black'))

Based on this post How to plot a hybrid boxplot: half boxplot with jitter points on the other half?, you have to use jitter.color = NA and jitter.shape = 21 in order to have the same color between the boxplot and jitter points

So, for your code, you should try:

library(ggplot2)
library(ggpol)

ggplot(all.bio2, aes(x = as.factor(season), y = S.chao1, fill= as.factor(season))) +
  geom_boxjitter(jitter.shape = 21, jitter.color = NA,
                 outlier.colour = NULL, outlier.shape = 1,
                 errorbar.draw = T,
                 errorbar.length = 0.2)+
  theme(panel.background = element_rect(fill = 'white', colour = 'black'))

It works for me (using mtcars dataset)

Example (using mtcars dataset)

library(ggpol)
library(ggplot2)
df = mtcars[c(1:20),]
ggplot(df, aes(x = as.factor(cyl), y = mpg, fill= as.factor(cyl))) +
  geom_boxjitter(jitter.shape = 21, jitter.color = NA,
                 outlier.colour = NULL, outlier.shape = 1,
                 errorbar.draw = T,
                 errorbar.length = 0.2)+
  theme(panel.background = element_rect(fill = 'white', colour = 'black'))
