It being Advent, when tangerines are commonly found at the grocers

Is that just a coincidence, or is there some symbolism that I'm unaware of?

The most traditional liturgical colours for Advent are purple (or violet) and a sort of royal blue. I never heard of anybody using the colour "tangerine" -- if indeed there IS such a colour -- to symbolize Adventide.

I just meant that things like satsumas and mandarins and tangerines tend to show up at the grocers around this time of year in the Colonies.
