to xxx
repeat 100 [setpencolor 1 + random 8 repeat 11 [for [i 0 359] [fd 1 rt
(sin :i / 2)]]]
end

xxx
setpencolor doesn't like 3 as input  in xxx
[repeat 100 [setpencolor 1 + random 8 repeat 11 [for [i 0 359] [fd 1 rt
(sin :i / 2)]]]]

setpencolor is not a single index it's a list of [red green blue]

I personally do not like much code on one line because it's too hard to
read and debug. You had 1 to many "]"'s also.

to xxx
repeat 100~
   [
   setpencolor (list random 255 random 255 random 255)
   repeat 11~
      [
      for [i 0 359] [fd 1 rt (sin :i / 2)]
      ]
   ]
end

But again I find organized colors much more appealing

to xxx
repeat 16~
   [
   setpencolor (list repcount*256/16 0 0)
   repeat 11~
      [
      for [i 0 359] [fd 1 rt (sin :i / 2)]
      ]
   ]
end
