Answer 1

There are two likely things that could have happened.

I suspect that seeds from a hybridization of the two have propagated. What you are seeing may be the dominant set of genes responsible for color.

Another possibility is a true mutation. This is quite common, but the color, here, leads me to believe that this is a result of seeds germinating.
