The resemblance is remarkable. In fact I was going to ask something about the cross with Citronella with your first mention, Pard; You answered it already. I don't grow either of them, but from pics it had seemed to me that the color of the flecking on Strawberries and Cream is more red, and decidedly more brown on Latvia. Yet the color on each of the two different hybrids are the same! So now I surmise that either/and:
--- the fleck color is indeed the same, but its human perception is influence by the background color.
--- the background color is bleeding through
--- there is some color blocking going on. White "genes" seem to have more of such a tendency.
