That only puts different colors on different axes. I was wondering
about the (silly) possibility of having a range of colors for the ticks
on a given axis.
I think you would have to either hack the code or issue
several axis() calls, e.g.
plot(1:9, 1:9, axes=FALSE, frame=TRUE)
axis(1, at=c(1,4,7), col.ticks=2, lwd.ticks=2)
axis(1, at=c(2,5,8), col.ticks=3, lwd.ticks=2)
axis(1, at=c(3,6,9), col.ticks=4, lwd.ticks=2)
Add col.axis=yourColourChoice arguments if you also want
coloured labels.

See `?axis' or try this:
plot(0:1,0:1, type = "n", axes = FALSE) box()
axis(side=1, lwd.ticks = 2, col.ticks="blue") axis(side=2,
lwd.ticks = 2, col.ticks="red")
