You don't give us much to go on. What device are you using? The
simplest idea is probably to change all the colours to black before
plotting.
palette(rep("black", 8))
should do that. This is assuming that mclust uses number for colours,
which as it is converted from S-PLUS code is likely.
A quick look suggests the only places colours are set are in clpairs and
mixproj and you could just omit the col= in
pairs(x, col=clrs, pch=symbols, labels=labels, ...)
plot(data[, 1], data[, 2], col=partition, pch=partition,
xlab=labs[1], ylab=labs[2], xlim=xlim, ylim=ylim, ...)
