<human>:  Are rainbows devoid of color made by mixing yin and yang colors?
<bot>: Yes, rainbows are made by mixing yin and yang colors. Yin and Yang are a philosophical Chinese concept represented by the color black and white. Black and white when mixed together create the color gray. The rainbow contains the colors: red, orange, yellow, green, blue, indigo and violet. The colors are not devoid of color, but are made by mixing yin and yang.
