Thanks for filing this Sam! 

I think the balance here is that too small an epsilon and we get precision errors, too large and we get bugs like the one I spent nearly all of my workday on today 🫠

However, we can definitely do better. At the very least we should say that the exact epsilon should be color space specific, and consider the extent of each coordinate. And hopefully define some bounds, so that the behavior is testable.
