Having both a color-unaware and color-aware versions can be really useful. Printing for example would retain the meaning without a gray-scaled rendition losing the details to understand what the symbol might be. (This is just a guess, not an assertion that black-and-white symbols would be used in this context.) From an accessibility standpoint, consider situations where high-contrast (and or size) is necessary, and it is perfectly legitimate to throw out or ignore the text and background colors for such users. This solution seems to best satisfy comprehension needs for disabled users as well as printers--not that we need to print the bible translated to emoji any time soon.
