I am trying to plot a ggplot2 point graph using

library(ggplot2)
ggplot(data,aes(x=EE,y=PE)) + geom_point( aes(color = factor(Me)))

and the plot is

I want to pick the color of my choice from the RGB or HSV or HCL and assign to individual factors or levels(Me) how can I do that?

How can I have proper colors assigned to unique(data$Me) values like c(red, blue, green, yellow, orange, black, brown, magenta, ...)

Thanks in advance.

Add this to the plot

+ scale_colour_manual(values = c('red', 'green'))

You can also use hex codes.

+ scale_colour_manual(values = c('#FF0000', '#00FF00'))
