Working on some code and was having a tough time configuring the color palette in GGally since it does not produce a ggplot object. It appears to be a larger problem. So, here is one hack, redefine the ggplot function and change the default palette there. Need to make a dyerlab::palette now…

ggplot <- function(...) ggplot2::ggplot(...) + scale_color_brewer(palette="Set1")
unlockBinding("ggplot",parent.env(asNamespace("GGally")))
assign("ggplot",ggplot,parent.env(asNamespace("GGally")))
require(GGally)
ggpairs(df,columns = 3:7,axisLabels="none",color="color")
