A common trope, especially in video games that feature Elemental Powers, is that every element will have a color associated with it. This way, you know that anything red is related to fire, blue to water, etc. This can manifest in many ways. Some common ones are enemies being the color of their element, element-resistant armor having that element's color, and elemental spells being color coded in menus. A few common examples of this trope follow. There are occasions where other colors are used for these elements, and these are by no means the only elements that get color coded.
