Yes, you do have few argument in your call to cons here:

(defun generate-candy-supply (size)
  (if ( = 0 size)
    (cons (nth( random (length candy-color)) candy-color))
    ;;    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ <= HERE
    (generate-candy-supply ( - size 1))))

cons needs two arguments, when you giving it just one. So with what are you cosing your color?

Also indent your code properly, now it's really difficult to read.
