Help - 3 Layer gelatin dessert ?

My mother used to make this wonderful three-layered gelatin dessert that she would buy in same area as Jello and puddings in the grocery store. This product was not made by Jello as best as I recall, ie I have taken a look at the old Jello 1-2-3 product page and do not think this is it. It had a texture that was somewhat like jello but much creamier and firmer. I think the prepartation was much like making jello and/or non-instant pudding.

Also unlike the Jello 1-2-3 product, each layer was of a different color and had a different flavor.

Anyone remember this? Can you provide me with a name of the product and or the manufacturer?
