What developers _should_ be doing is disabling such animations if `prefer-reduced-motion` is set in your browser. This way, both people who have trouble seeing stuff when there's too many complex color animations as well as people who "just don't want to deal with all that mess" can specify what they want to see, and the code can change based on their preferences.
Unfortunately, I believe for "custom jobs" like this you'd need to explicitly state that you don't want it to occur because it won't happen by default, unlike some other stuff that's more standard in the browser.
