I\'m currently using scale_brewer()
for fill and these look beautiful in color (on screen and via color printer) but print relatively uniformly as greys when us
ggplot can use colorbrewer palettes. Some of these are "photocopy" friendly. So mabe something like this will work for you?
ggplot(diamonds, aes(x=cut, y=price, group=cut))+
geom_boxplot(aes(fill=cut))+scale_fill_brewer(palette="OrRd")
in this case OrRd is a palette found on the colorbrewer webpage: http://colorbrewer2.org/
Photocopy Friendly: This indicates that a given color scheme will withstand black and white photocopying. Diverging schemes can not be photocopied successfully. Differences in lightness should be preserved with sequential schemes.
