Unfadingly → It is formed from "un-" (meaning not) and "fading" (from the root "fade" which comes from Old English "fadian", meaning to lose brightness or color) and the suffix "-ly" (meaning in a manner). The word "unfadingly" means in a manner that does not lose brightness or color.
Think of 'not' ('un-') losing brightness ('fading') — that's why 'unfadingly' means something that remains bright or vibrant.
