unfadable
Resistant to dimming
Unfadable means incapable of fading or losing intensity.
The word appears in two main contexts: describing materials or colors that resist fading from light or washing unfadable fabric dyes, and describing qualities or memories that remain vivid over time an unfadable impression.
The latter use carries a note of permanence or endurance: Her unfadable spirit inspired everyone around her.
