My solutions to the problems you raise, in order of preference:

1. Not worry about it, it probably won't happen on the projects I'm working on. YAGNI.

2. OK, it's happened. Get some coffee, make all the changes. Can I use a regex? Make the changes incrementally? Delegate it to a junior?

3. This is going to change a lot. Let's make a re-usable component, a named colour like 'primary' (in Tailwind config), or re-usable class like .button-default. The right solution will depend on the requirement.

In styling, I'd rather have 1000 obvious changes than 1 difficult one. The risk of having the wrong shade of red is not high enough for me to worry about abstracting it.

I appreciate that good, full-time CSS devs have much better solutions for this, but those solutions involve being good at CSS as a starting point. I don't have that luxury.
