[R] hcl()

[Robin Hankin]

Hello everyone

I am struggling with hcl().

It says on the manpage that   "240 yields blue".

With this:

plot(1:50,pch=16,col=hcl(h=240, c=50, l=1:50))

I get mostly blue, but also some red, dots.  Note that h=240 
throughout.  If 240 is blue,
how come there's a red dot there?  Or is it just my monitor?

Can some colour expert help me on this?
