Thank you for the kind words, Otared,

Regarding the colons (and other symbols with "dots"), I would say it
is still not optimal in Lucida (and difficult to make it "consistent",
there are too many symbols that are at the moment different). But in
your example you can use \colonequals and \colon if you prefer. They
are centered around the math axis.

Best, Mikael

\setupbodyfont[lucidaot,12pt]
\starttext
\startformula
f(x) := -(u|x) \colonequals - \langle u, x \rangle
\stopformula
\startformula
f : A \longrightarrow B \breakhere
f \colon A \longrightarrow B
\stopformula
\startformula
\mathaxisbelow := \colonequals : \colon
