The white veladora is used mainly to ask for peace, general protection, and spiritual cleansing. It's the most common entry point into the devotion, and it's also used to give thanks for favors already received.
It's the usual starting point for anyone new to the devotion, since its petition isn't tied to one specific area of life.
Giving thanks doesn't have one assigned color. Many devotees use the same color as the original petition that was granted, as a way of closing that particular cycle.
When is it used?
It's lit to ask for calm, general protection of the home, or simply to "open the way" before a more specific petition with another color.
How is it combined?
Many devotees combine it with a black veladora and one in the color of their specific petition, forming a small triangle of three candles.
