This evening I was surfing the VHF channels with my CT-100 and came across a game with players sporting big-time red jerseys. Grabbed my camera and added this example of a CT-100 displaying interesting red to my site.

FYI: Here's the intro to the page.
The very non-orange 1953 NTSC red is very inefficient. Red phosphor is blasted with at least twice the energy of the other primary colors in the 15GP22.
It is, therefore, common for the red gun in a 15GP22 to be weak compared to its blue and green partners. The procedure for getting good color balance cuts back on the blue and green during setup and leaves some headroom, so that, although the resulting video image will be less bright, it will nonetheless reproduce a picture with minimal electrical and phosphorescent distortion.
Here is an over-the-air example of red from an eyeball-balanced CT-100 with a good red gun. Plans are forming to calibrate the set using instruments in early 2007 that will ensure, among other parameters, a correct Illuminate C white.
