Colors have meaning in magic, and the specific meanings vary between cultures and individuals. Back in the 2000s, I started developing my own system of color symbolism based on what made sense to me. 

This requires a bit of background - please bear with me.

I had been working with a common Western model of the energy centers in the human body and that formed part of the foundation. 

Subtle energy is the stuff that everything is made up of, when it comes to magic, and the human body typically has energy centers where it's especially concentrated. The centers have different functions like the organs of the physical body do. But as I learned, the model I was taught is not accurate to the original teachings from the East that were modified to create the common Western model of 7 major energy centers with a rainbow of color associations, and not everyone has the same energy centers in the same place, doing the same things.

I'm not very visual when it comes to sensing subtle energy; I'm more tactile. So it's okay with me that I relate colors to energy centers based on symbolism and not what I'm "seeing" when I "look" at my energy body. The colors I associate with the Western Pagan elements became part of the meaning I found in this system I was developing.

I pay attention to more than the 7 energy centers in the model I learned back then, so I needed to add colors. I want to emphasize that this was well before the Progress Pride flag was shared with the world, and I didn't base my color associations on anything involving race or gender. I am all for smashing stereotypes rather than enforcing them.

With that said, what I got was a system of 13 centers and colors, each relating to a different set of themes. While most of them form a vertical column when viewed as energy centers in a body, I also see their essences as a cycle with no top or bottom, no end point, and none better than any of the others.

Silver: Hidden factors, the underworld, underworld deities and spirits, more covert or tricksy deities and spirits. The ancestors usually fit here for me, but I know that's partly a matter of how I relate to my ancestors of genetics and marriage. That's my baggage, and you may consider Gold more fitting for some or all of your ancestors when using divination methods where I rely on colors.

Black: Living community. This includes animals, plants, and the Earth as well as fellow human beings, but it is creatures of Earth - if you work with the Fae or other otherworldly beings, that's Silver or Gold, most likely Silver.

Brown: Boundaries - the limits you choose to have for yourself and the things you do, or don't do, as a result.

Pink: Receiving - physical gifts, obviously, but also getting things like kindness, compliments, and assistance. Your willingness to accept these things and how it makes you feel.

Red: The Will, determination, drive, and motivation, action. Will has a specific meaning in some magical traditions, relating to your highest expression of your self, but you don't need to use that definition if you don't belong to such a tradition. 

Orange: Creativity, change, and the future. Creativity includes making things of all kinds, regardless of whether it's art and whether you're an artist.

Yellow: Self, identity, the body, physical belongings, money, stability

Green: The mind, intellect, circulation (such as breathing and your blood flowing, and anything symbolically similar).

Light Blue: Giving - like Pink, this can be physical things or less tangible ones. Your willingness to be generous and how it makes you feel.

Dark Blue - Emotions and feeling.

Purple - Magic, intuition, breaking things down into their parts or letting them decay, the past, letting go. 

White: Your Higher Self (which has a specific meaning like Will, and the same thing applies), being your best self, the amalgamation of all the things you have been and will be, communication with your Higher Self/best self/who you were or will be.

Gold: Deities, spirits, and guides, particularly ones who are more straightforward and/or "what you see is what you get"; otherworlds of similar description, perhaps ancestors.

This system came from my understanding of myself and is not always able to be generalized to other people energetically, but it still provides a framework that covers many of the things a divination client may want to know, so I've used it as the basis for my divination dice and my first charm casting maps.
