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? -- Robin Hankin Uncertainty Analyst
