Well, you need to change one (the burst or the subcarrier in the picture) relative to the other. It's a routine operation for processing amplifiers (proc amps).

Actually to affect NTSC modulated signal you need to adjust color burst only because it is used as the reference for demodulation process. If you change the subcarrier used for the burst and the actual signal there will be no change. By reducing amplitude of the color burst you will increase color saturation and by changing its phase you will adjust the hue. However, changing burst will make a not standard NTSC - the color bars will not be in standard location on the vectorscope.

Can you do that in PAL / NTSC without demodulation?Sure! Adjust subcarrier amplitude for hue and phase for saturation.
