My understanding is that with corn, genetic variability is a big factor, withe in breeding leading to much smallergies kernels/cobs. . I suspect your varieties have crossed. And that corn plant is exhibiting hybrid vigour. You typically need to save seeds from about 200 plants to prevent inbreeding depression in corn.
It's unlikely that the corn has crossed with field corn, as, genetically, field corn doesn't contain the genes needed to show the pretty colours that mutant cob has. It's possible, of course, that a few kernels have crossed with field corn, but it looks to me that you are seeing the results of a cross last year, and also, based on the multiple colours, more crossing this year.
As for the multiple colours - its possible that the speckling is a trait that was hidden in the Aztec corn. My Painted Mountain corn has lots of speckled kernels,

This year the ground temperature at our farm didn't get warm enough to sprout until the last few days of May. I have noticed that our timing is messed up too. We grow an old line of dent corn that accidently gets pollinated with our sweet corn and flint corn sometimes. The only thing we have that doesn't seem to cross is our strawberry popcorn. This year the wind has seldom come from the west like other years. It definitely looks like it was crossed with a dent corn.

Looks like they also receive samples in the mail if you wish for them to test it for you. You would want to ask the test kit company what protein exactly they are testing for ..... I suspect most field corn might be GMO for the Roundup-Ready trait, but it would be interesting to ask. How far away from your garden is the nearest field with standard field corn?
