Good thing you caught it in time! Often outrageously flashy goat kids are scams, especially if the seller seems to ONLY have flashy kids (no plain ones) and especially if the background and/or photo style are significantly different like those are.
But to answer your question for future reference, moonspots are dominant so either doe would have worked fine for your purposes. I have found that the heavily moonspotted goats often produce kids with few or no moonspots, however. On the other side of the coin, plainer goats with only a couple small moonspots can produce some really flashy moonspotted kids. It's a total crapshoot, but one parent does have to have moonspots.
Even if you're breeding only for color, I encourage you to also take conformation and quality into consideration when choosing goats, especially since moonspotted kids are never a guarantee
