Unless you can get that same formica/laminate... I don;t think it would be a worthwhile cause. Even if you could find the same pattern, the age difference might be pretty obvious when compared side to saide due ot different dyes used then and now (as an example) as well as possible UV fading (sunlight coming in through windows) etc.
If it was a wood veneer, the same pretty much applies, with staining and what-not.
Of course I could be incorrect, and there is an easy fix out there. If there is, I surely hope someone can post it
