What does psychological khaki mean?

Some colors are unique to the country ~ such as green ~ blue ~ red ~ white ~

Although khaki is warm, it can also give people a slightly warmer visual psychological feeling. However, because its lightness and chroma are not high, if we analyze it from people's personality, it seems that he is a relatively stable, down-to-earth and well-loved good man who likes to help others in the dark. In fact, it is more appropriate to describe khaki with the phrase "a person can't judge by his appearance, but the sea can't measure it."
