The first type of response is the large color block echo, such as the picture below, the silk scarf and the jacket are warm yellow. The warm yellow of the long coat is the main color, and the area is large. If the silk scarf is tied to the neck at this time, the position is too close and completely yellow. To highlight the scarves, you can only use the hair band, the upper and lower echoes, and the color distribution also has a breath. It should be noted that the so-called echo does not necessarily mean the same color. If the wool coat on the picture above is replaced by navy blue, the headscarf is warm yellow, and the contrast color is also used.
