Here is a mish mosh of color meanings that I use in my own rituals, including my upcoming Vernal Equinox Ritual.
Orange: Encouragement, Adaptibility, Stimulation, Attraction. Also, creativity and the 2nd chakra.
Yellow: Attraction, Persuasion, Charm, Confidence. Also, cheerfulness, matters relating to self-esteem and the third chakra.
Green: Finance, Fertility & Prosperity of all kinds, Luck. Healing. Also associated with the heart chakra (though use pink for attracting romantic love.)
Blue: Tranquility, Understanding, Patience. Also, communication and associated with the throat chakra.
Purple: Spirituality and the third eye and crown chakras. The color of royalty. And because to its connection with Amethyst I use purple for protection.
Pink: Romantic Love. Self-Love.
Black: For power.
White: All inclusive. Protection. “The Highest Good.” Neutral.
