It is quite likely the source, the Atari joystick. Either the colour sub carrier is slightly off frequency or the chroma is low. Sony sets are particularly fussy about this.

When I worked in the cable TV industry no colour faults from customers when it appeared OK leaving the headend always seemed to be those with Sony TVs. The fault at the headend was something like a poor connector causing the chroma to be very low.
