Your TV must be a color set, as there is no "killer" control on b&w sets.
It has been some time since I worked with analog color TVs, so I am going by what I remember. Analog CRT color TVs had what was known as a "color killer" circuit, which shut off the color processing chain in the TV when a black-and-white show was being telecast. If the killer is misadjusted or inoperative, color interference will appear in b&w pictures. The killer adjust potentiometer regulates the point at which the color killer starts to work. If the control is set too high, it will firmly cut off the color processing circuits, resulting in a b&w picture even on known color programs; if too low, color interference will appear in known monochrome (black and white) pictures. The correct setting is that at which the color interference just disappears from the picture, which will ordinarily be at or near the center of the control's range.
