I have been including the color associated with each Major.
Most color correspondences are based on the Cabala, and they work well in terms of Tarot. Yellow (The Magician) is a bright, vibrant happy color; Blue (The High Priestess) is cool and soothing; Green (The Empress) suggests fertility and abundance.
Colors have the ability to affect our mood and thinking a few minutes about the color associated with each Major Arcana card will give you clues about the mood of the card.
