What an interesting take on color. Colors of the rainbow and the seven major chakras of our bodies. Color helps us put a light on our focus or perceptions.
Just now looking at these cards, the color of the five elements in Chinese astrology and Feng Shui are present. Fire, Earth, Wood, Water, and Metal. Fascinating. The card meditation gives us: if there are times we are feeling low or lethargic, for example, to meditate on orange or yellow to uplift and energize us.
