    Re: "Illusions" —Mike Thorn
   (...) I was trying to make the flame pieces a little more transparent. I thought there were a little too "strong." It was just a little overbearing. I've used rgbt to great success before with the (URL) Town Square Fountain>, so I thought I'd try it (...) (21 years ago, 2-Mar-04, to lugnet.cad.ray, FTX)

   (...) Not exactly, but pretty close. The 100 looks like it might be about right, but the 010 is more purple than magenta, and the 001 is clearly yellow and not amber (the nofilter flames look closer to amber).
