What color clothes should I wear to take photos when traveling in Qinghai?

Whether this looks good or not is not determined by the same color of clothes. It has something to do with your own conditions and the technical level of the photographer. If your skin is dark and fat, you can wear dark clothes, which will make you look white and thin. If you have a good figure and are white, you can wear light clothes, which will look fresh. In a word, I suggest you learn to dress. People dress reasonably and their photography skills are not bad, so the effect will not be bad.
