According to Greek mythology, if you are touched by King Midas, everything you touch will turn into gold. This ability is known as the "golden touch" or the "Midas touch". However, King Midas himself regretted his wish and cursed it when he discovered that even his food and drink turned into gold in his hands. Therefore, being touched by King Midas would not turn you into a specific material, but rather everything you touch would turn into gold.
