This code did not produce the plot you have linked to. The answer to
your question depends on how you created the plot, so you have to tell
us that. Changing the color in all panels is easy:
histogram(rnorm(100), col = "goldenrod")
Different colors in different panels is a little more work:
histogram(~rnorm(100) | gl(3, 1, 100),
mycolors = sample(colors(), 3),
panel = function(..., col, mycolors) {
panel.histogram(..., col = mycolors[panel.number()])
})

columns <- 8:153
plots <- vector("list", length(columns))
j <- 0
for (i in columns)
{
?plots[[ j <- j+1 ]] <-
? ?histogram( ~ data[,i],
? ? ?ylab = "Frequency", xlab = "Score",
? ? ?xlim = c(1,5), ylim = c(0,100),
? ? ?main = colnames(data)[i]
? ?)
}
print(plots[[1]])
# or export
for (i in seq_along(plots))
{
?png(paste("hist", i, ".png", sep = ""))
?print(plots[[i]])
?dev.off()
}
