We can use this theme as shown below: Scale_color_brewer() for lines and points # box plot bp + scale_fill_brewer(palette = dark2) # scatter plot sp + scale_color_brewer(palette = dark2) usage in base plots. Within your standard ggplot code wrapper, i have tried gradient2 scale_colour_gradient2 (low = grey, mid = red, high = grey, midpoint = 25) + and gradientn; Using the labels parameter of the scale_colour_discrete function, we can pass a vector of values by which we can substitute the existing scale labels.
