[R] barplot default colors

Dear R-help,

Can some one explain why barplot() uses changing colors in the bars by
default?  I should think that most of the time when people draw barplots,
they want the bars to be in the same color.  (At least that's what I'd
expect.  The first time I used barplot() in R, I was shocked to see the
colors.)  As an example, one example in ?layout draws a scatterplot with
histograms drawn on the margins.  The histograms were drawn by barplot(),
and, IMHO, look rather hideous in the colors.
