It makes sense I suppose - strangely, most of the laserdiscs that have
the test pattern never explained how to use it. I did not know until I
bought "A video standard" laserdisc and those blue THX glasses.
Anybody with a proper sense of color can adjust the display without the
blue glasses. There's nothing THX about them, just a deep blue filter.
The real key is getting the white temperature at 6500K for every 10%
step from 0 to 100 % brightness then throw away the blue filter and
set the tint in the center. Only exception would be if the color
decoder is really bad in the TV. The turn down the color to remove
any over-saturation. Issue is owning the test equipment to measure
the 6500K, that is expensive. If no test equipment use the blue
filter and adjust the tint to balance the RGB but you are only setting
it for only one input level verses the 10 steps from 0 to 100% with
the white pattern.
