In fact, ordinary micromagnetism (or weak magnetism) is composed of black metal (usually iron and its compounds), so it is black.
However, if it is a strong magnet, it is composed of rare earth metals (such as cobalt, boron, europium, iridium, etc. and their compounds). So they are all white.
Common magnets are made of ferroferric oxide, which is black, so common magnets are black
