The Color help file says: *rand(hue, sat, val, alpha) create new random color. but the Color class method is: *rand { arg lo=0.3,hi=0.9; ^Color.new(rrand(lo,hi),rrand(lo,hi),rrand(lo,hi)) } so help file should say something like: *rand(lo,hi) create new random color with red, green and blue values between lo and hi.
