What does Taoism mean by wearing yellow gas and purple gas?

As far as I know, each branch has the same and different views.

Reason.

The theme of Taoism is Yin and Yang, which comes from people's hesitation in the growth and seasonal changes of Yin and Yang, that is, the Tai Chi string in the middle, representing people, that is, the three talents of heaven and earth in Taoism. Because people are born of yin and yang, yin and yang must be endowed with qi, so Taoist people look at qi, that is, yellow qi and so on, and look at the natural qi in people.

As for what you said about Qi, there are many explanations in the branch of Taoism.

For example, in this branch of Taoism, yellow gas represents the qi of emperors, which is dignified and auspicious. Purple gas represents expensive, and ordinary nobles represent purple gas.

Maoshan and Huang Qi exude the Huang Wu Qi from the grave, which is the fiercest and most imperceptible of all fierce Qi. And purple gas can't be too much, too purple is also a fierce wheel, and there is black gas and so on.

The divination branch of Taoism, such as Zhantian, the yellow gas represents the gas of Huang Xuan, which is the vital qi of the hit, indicating that the weather is clear and there are no clouds in Wan Li.

In Taoism, it is also the face, body shape and yellow gas of divination, and purple gas represents the murderer.
