Assigning multiple colors

[ArbyE]

Hello everyone and thank you in advance.

Currently I'm learning R through a course and I have a question I can't seem to figure out or find the answer to. I'm working with the "palmerpenguins" data set and wanted to know if I can assign a specific color (of my choosing) for each species of penguins.
I know I can write :
"color = species" in the aes function and
"color = 'red'" outside of the aes function to make the plot Red.
Would I have to assign a specific color to each type of penguin and then incorporate that into the code?

You can use scale_color_manual() in the same way I have used scale_fill_manual().

DF <- data.frame(Species=c("Emperor","Cape","Hoboken"),
                 Value=c(23,34,19))
library(ggplot2)
COLORS <- c(Emperor="red",Cape="blue",Hoboken="green")
ggplot(DF,aes(x=Species,y=Value,fill=Species))+
  geom_col()+scale_fill_manual(values=COLORS)

Thank you so much. It took me a second to figure out how to apply it, but it worked.
