Each color has many meanings and is very useful in various practices. Such practices include: evoking feelings and emotions, healing chakras, aiding in the law of attraction, spiritual healing and pathwork, and much, much more.
You can use colors in passive color therapy by wearing corresponding colors. You can decorate your home in certain colors to set the mood, or for color therapy. You can also use colors more directly and actively by use corresponding colors via candles during spells, sachets, crystals during healing/meditations, ink for drawing sigils/writing spells, etc. Any workings you will be doing, can always be spiced up with a bit of color.
