Well... There is nothing about the Moon itself that would do this. It would have to be something about the Earth's atmosphere itself. Usually orange or red colors at moon rise and moon set are due to dust in the atmosphere. I do not know, off hand, how a yellow Full Moon would happen consistently during the same season, although there are seasonal variations in Earth's weather systems. But why this would make any difference, I just don't know. Perhaps a meteorologist 'out there' could tell us more!
