In the examples I mentioned (below), running ‘context’ on the first produces large colons, whereas ‘luatex’ on the second does not. The latter looks right to me.
There is a similar issue with integral symbols, where somehow ConTeXt add additional spacing after it.
— context —
The function $f: A → B$, $g\colon A → B$.
— luatex —
The function $f: A \to B$.
