Well, you can make the colon active in math mode and then let it output \colon.
This is a TeX way, I don't know if there's a ConTeXt way for this:
\begingroup\lccode`\~=`\:\lowercase{\endgroup
\let~}\colon
\mathcode`\:="8000 %
For some reason, the colon in ConTeXt is larger relative LuaTeX.
you probably mean latex (macro package) here as luatex (engine) itself doesn't
do anything
keep in mind that context implements much of math in a complete different way,
so solutions for problems or wishes are done differently too; in this case we
try to use unicode and some lua magic instead of character juggling at the tex
end
we also need to keep in mind that characters have to behave well in tagged pdf
and exports and so
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.
define 'luatex' ... it's all about choices that macro packages make (or
made in the past)
There is a similar issue with integral symbols, where somehow ConTeXt add
additional spacing after it.

\starttext
The function $f: A → B$, $g\colon A → B$.
we could add a mathsymbol entry but I leave that to Aditya to decide
{
adobename="colon",
category="po",
cjkwd="na",
description="COLON",
direction="cs",
linebreak="is",
mathclass="relation",
--mathsymbol=0x2236,
unicodeslot=0x3A,
},
