Regarding Combat Hero Optimus and Megatron repaints

Were the yellow / green Combat Hero Megatron and the dark blue / purple Combat Hero / Decepticon version of Optimus released in 1993 alongside the standard color (http://www.cliffbee.com/reviews/images/heroprime.gif)? I have these guys loose and there is 1993 printed on the bottom. I also have the standard red and white hero prime with 1993 printed on the bottom.
I remember getting the red and white Optimus new in the store but I don't remember seeing the the others on the same rack. I figured these were repaints released alongside the normal color. I remember choosing my turquoise green G2 Grimlock in mix of other colors on the rack at a Carefour when they were in the US. My mind went against logic and did not choose the standard grey Grimlock.
