from math import dist

def nearest(self, red, green, blue):
p = red, green, blue
distances = {name: dist(p, q) for name, q in colors.items()}
return min(distances, key=distances.get, default='')gives

Possible overloads:

(iterable: Iterable[_T1], /, *, key: (_T1) -> SupportsRichComparison, default: _T2) -> _T1 | _T2

I'm not quite sure what pyrefly is complaining about, since it definitely is a valid use case, although perhaps a bit odd.
