White is not a color in the traditional sense, but rather the presence of all colors combined. This is why white light can be split into a rainbow of colors using a prism.
White is often associated with purity, innocence, and cleanliness in many cultures, which is why it is commonly used in wedding dresses, hospitals, and cleaning products.
White can also have negative associations, such as with death or mourning in some cultures, or with emptiness or lack of creativity.
