I tried to add "col=1:8" in the "auto.key", but it changes the colors of the text of my Legend, not the lines. How can I change the colors of the lines?

xyplot(estimated ~ year, data=res, type="l", group=sp,
par.settings = list(superpose.line=list(col=1:8)),
auto.key=list(points=FALSE, lines=TRUE, corner=c(0.1,0.6), size=5))
