All red is 3 mil stylus for 78s.  All green 1 mil for 45s.  Half and 
half a 2-mil "compromise" that plays both poorly but is recommended by 
some for repro 78s.  That is the original Zenith color code. 
Reproduction manufacturers may not follow it accurately.

Old stock Cobra carts can be hard on stereo 45s as they have poor 
vertical compliance.
