Hey there!
Please remember that this is my interpretation of this as I am writing this. Ask me on a different day, or ask another Witch all together and you may get a completely different answer :)
Let's talk about colors.
Magick is all about intention and energy, right? Part of intention setting and energy can be focused on colors and the different things colors can do, which is pretty cool because that's just one more tool in our "tool bag".
