So clearly color science is a different type of interest for me than cosmology is.
It's a recurring, supporting interest that continues to crop up in a few different contexts. I rarely actively seek to learn about it for its own sake but it's always enjoyable when I come across it in the context of another pursuit and I can strengthen my knowledge of it.
Is it possible I could go through a phase where I just want to focus all my time on color science? Possibly.
But it's also an example of where I can reduce too much churn and trading-off of other interests by recognizing that color science (and particularly the sorts of things I've talked about above) is something I enjoy learning about and which contributes to my understand of a bunch of other things but it need not itself be a driving passion of mine.
That said, it's not easy to put under a single persona.
