Some text in this card was black, instead of neutral. When text is strictly black, it causes it to appear black even when the user's device is in dark mode, making it hard to read. When in the neutral setting (that's what I call it anyway. This is the default color, and the setting of all other text in this deck and most anki cards in general), the text will appear black when the user is in "light mode" and white when the user is in "dark mode." Again, this is the "color" of the text in all other cards in this deck, and for some reason these do not adhere to this format, probably because they were copied from an external application.
