Early color television in 1967: Is it PAL or NTSC?

[blue_lateral]

There are some American NTSC tube sets which had a front panel control for the CRT screen grids for color balance (in addition to the phase control for chroma, which is usually called "tint" or "hue".)
The control for the color temperature, controlling the CRT screens was often called color fidelity, chromatone, or chromix. You could adjust for a "sepia tone" on b/w programs by using this control, or make the picture more blue, etc. similar to what can be done on some computer monitos.

The first works-in-a-drawer quasars (solid state) had a control like this, too. There was a "tint" control for color temperature, and a "hue" control for chroma phase.
