  • red is shorter than any other color! :D
  • u/firegodjr
    Looks like a rose :D
  • u/Agnes
    For the record, strokeStyle="tan" is as short as red.
  • u/magna
    R(k) also seems to work
  • u/zanella
    You can replace 1.57 with 1.6, and use this extra byte to use hex colors instead of red, like #0f0. ;)
  • u/zanella
    Or, if you want to keep it really precise, replace *1.57 with /.64.
