What does that mean?

But can one not have it only in math, the way you suggested before, as in the code below?
Anyway, for Unicode fonts that support RATIO U+2236, input : COLON U+003A should properly give that RATIO in the output, and \colon should output a COLON. :-)
\setupbodyfont[xits,10pt]
\appendtoks
\catcode`:=\activecatcode
\letcharcode `: \colon
\to \everymathematics
\starttext
Note: the colon in text should behave normally.
\startformula
\startalign
\NC f\NC\colon A→B \NR % Outputs ∶ RATIO U+2236
\NC f\NC: A→B \NR % : COLON U+003A, outputs ∶ RATIO U+2236
\NC f\NC ∶ A→B \NR % ∶ RATIO U+2236
\stopalign
\stopformula
\stoptext
