If I understand what you want correctly, you'll probably want to use the
"col" argument in whatever base graphics function you're using, rather than
changing something in the graphical parameters. For example, if I wanted to
add red points to an existing plot, I would use something like
points(c(1:10), col="red")
Or, if I wanted to generate a barplot using a shading color other than gray,
barplot(c(1:10), col="steelblue")
Does that answer your question?
