That’s something I want to know too, reader Dean. They aren’t named for the birds, I know that much. Which leaves only church Cardinals, presumably of the Catholic variety. Various entries I’ve found on cardinal slices claim that the colors of the pastry — gold, white and (at least traditionally) red — correspond to the colors of the Catholic Church. However speaking as a Catholic, I’m fairly certain that the church doesn’t have an official color palette. It has the cross — its official “logo” — and the colors of the liturgy, which is to say the various colors that are associated with specific celebrations or times of the year.
There are five official liturgical colors: white, red, green, violet and black. Each has a specific symbolism: white for light, joy and resurrection; red for blood (or fire); green for life, hope and renewal; violet for sadness and affliction, and; black for mourning, sorrow and death. To these the color rose (for joy or happiness) is sometimes added. Gold isn’t a liturgical color, strictly speaking, which is not to say it’s frowned upon in any way. By no means. Gold is everywhere in Catholicism as it symbolizes not only preciousness, but the presence of God. It’s a common color in the vestments of the clergy (it can technically replace white, red or green as a liturgical color), and is often worn on key celebration days like Christmas and Easter, Holy Days or at weddings.
