Try setting something like "cex=0.5" in the plot. It works for at least hclust. Here is a quick example using hclust to show how you can get away with set the colours.
data(USArrests) hc <- hclust(dist(USArrests), "ave") plot(hc, hang=-1, cex=0.5) labels <- rownames(USArrests)[ hc$order]; n <- length(labels) mtext(labels, side=1, at=1:n, las=2, col=1:n, cex=0.5, line=0) If you want to get rid of the double labelling (which is useful for checking), then set "labels=FALSE" in the plot(). The trick now becomes how to generalise this to other dendrogram and when "hang=-1" is not the case. My initial though was to look into plot.hclust to see how the coordinate for label placement was calculated and replace it with text(..., col=col.label). But it appears that this is done with a ".Internal" function and I have not learned how to read/edit this yet.
