Original LT5 spark plug question???

[Roadster]

Does anyone know if there was any difference between the early and later years with letter coloring on the original LT5 spark plug wires? Did the later years letters appear to be more white in coloring?

My 95 has white lettering!

So does my 94, but I also have a set from a 90 and the lettering looks to be on the grayish side. Just curious if there was a change during production.
Thanks for the reply!!!
