Interesting question. I think of colors fading when I pondered the question. Colors with my experience do fade becoming lighter shades until nearing white. In other words the color changes.
In essence one may ask does the color ever really diminish and is not there any longer? Can a color be restored or become more invigorating? Does that consider Love may have agency? So, is color a good analogy for Love in the case of this question? Perhaps a cup'pa tea and some more pondering . . .
To ponder first is to understand Love is an abstract noun. (Kinda' technical perhaps) Therefore it's meaning is esoteric and varies by individual first and then by groupings of two or more. So, with a couple for instance meaning should have some sameness and is immeasurable IMO. In other words is unconditional.
To offer a little from a personal perspective I began a Hub on Love at the first of the year. It grew to become fifteen rough Hubs. Most Hubs were seeking and exploring meanings in different disciplines. Those areas explored were:
General - Impersonal and Interpersonal
Science - Biological (Neurological and Psychiatry)
Science - Psychology and Emotions
Social Psychology - 5 Perspectives with emphasis on Symbolic Interactionism and Social-Cognitive
Cultures - Key world cultures
Philosophy - Western and Eastern
Religion - Key world religions
Apologetics - Philosophy within key world religions
Spirituality - Meaning with emphasis on God, gods, the cosmos, and etc.
Belief - A Key to Love with emphasis on acceptance, faith, and trust
My studies focused on Love and not all the stuff. As it progressed it became mind boggling at times. However I discovered many parallels too. It was exciting, intriguing, frustrating, and enlightening too. I have set it aside and may go back to it once again. I still am digesting information learned.
With the question above I ponder if the color faded or became more invigorating as I studied seeking meaning for 'Self'. I think at times it did fade or meaning changed. Perhaps it did fade and that was why I set it aside? Or, did it simply arrive at an acceptable shade awaiting further change?
