Colored salt is salt that has been artificially colored, often with food coloring, to enhance its visual appeal.
While the provided YouTube Shorts description alludes to a method for testing the purity of salt by dissolving it in water, it doesn't directly define "colored salt." The implication is that the color might come from impurities, but intentionally colored salt exists as well. The purpose of the video is to check for impurities in salt that shouldn't be colored.
Therefore, considering common usage, colored salt is often used for decorative purposes, such as in bath salts or craft projects. It can also be used in cooking, although caution should be exercised to ensure the coloring is food-safe. The video suggests you can test for what the color is by dissolving the salt in water and seeing what remains after the salt dissolves. If the color settles, it suggests it is not purely salt and might contain unwanted additives.
