How can I determine the spectrum of incident light on a sensor,
in general?  Then, how many corners can I cut to sacrifice resolution
and accuracy?

How broad and how much resolution?  There are sensors, eg:

versions of which can be found in cheap dev boards:

I'm sure I remember reading recently of a consumer grade multispectral
camera part with a moderate resolution (something like 8x8 or 32x32) but I
can't find a reference to it now.  But it seems there's a phone launching
with such a camera soon (according to rumours):
