Also, in White Umbanda, part of the 401 Orishas religion of Nigeria which was exported to Brazil (with a slave system far worse, in terms of sheer numbers, than even the deep South) the color yellow is sacred to the fresh water goddess Osun (as opposed to the mother Goddess Yemaya, associated with salt water) along with brass, jewelry, the so-called 'inner head’ and hairdressers, beauty (in general) and ducks (and curiously vultures), and with money in the form of cowrie shells.
There is another (male) deity known as Ogun, and in the translation to the New World, Osun becomes Oxun in Spanish and Oxum in Portuguese if I have that correct. Brass becomes gold (or bright yellow) fresh water waterfalls and ducks are replaced by macaws.

The Brazilian dancers of the Capoiera were continuing traditions which were outlawed, they were sublimating hegemony in the most sublime way, teaching their revolutionary fighting style right in front of the Master’s faces. So too, the Oxum dancers in their sacred yellow trotting out each year for Carnival were sublimating the Catholic hierarchy which gave nodding approval to the debasement of the human soul but forbid sensuality expressed through cultural memory.
