Do the colors of dreams and objects affect your health? Do different colors represent different emotions? If so, what does each color stand for?

It won't affect. Scientifically speaking, red is exciting, yellow is nostalgic, blue is melancholy, green is relaxing and black is calming. Of course, it's not right, because red has light powder and deep powder. As well as personal hobbies and experiences, just like the color your idol likes, you can't help liking it. My wallpaper is light green, so it's easy to be quiet.
