Message-ID: <8703130502.AA19921@ingres.Berkeley.EDU> Date: Fri, 13-Mar-87 00:02:29 EST Article-I.D.: ingres.8703130502.AA19921 Posted: Fri Mar 13 00:02:29 1987 Date-Received: Sat, 14-Mar-87 00:33:51 EST Sender: daemon@ucbvax.BERKELEY.EDU Organization: University of California at Berkeley Lines: 8 In my posting explaining the basics of color perception, I consistently made the error of switching the terms "rod" and "cone" (my upcoming article on low-level brain damage will explain why). If you switch these terms throughout the article, it will be improved, and perhaps even correct. So: cones come in three color-sensitive flavors, while there is only one kind of rod which is used in dim lighting. Doug
