IPA: //ʌnˈfeɪdɪd//
KK: /ʌnˈfeɪdɪd/
Not having lost color or brightness; still vivid and clear.
The unfaded colors of the painting made it look as if it were created yesterday.
Unfaded → It is formed from "un-" (meaning not) and "faded" (from Old English "fadian", meaning to grow pale or lose color). The word "unfaded" means not having lost color or brightness.
Think of 'not' ('un-') having 'lost color' ('faded') — that's why unfaded means something that retains its original color.
