(ONE) I would like to approximate the color temperature of various
light sources. This is for use in general photography.

(TWO) I would also like to approximate the color temperature of the
ambient light in a room after it has been reflected by the various
surfaces.

Is there a way to measure these color temperatures using the sort of
equipment which might be found in a home workshop of an enthusiast?

I have not used it, however Expodisc does just this.

I personally shoot in RAW and if the colour temp is not right, correct it in
post production. Adjusting the colour temp does not reduce the quality of
the pic.

If I were going to play with this idea, I would take a picture of some
neutral object under sunlight, then take a picture of the same object
under the light in question. Use RAW conversion software, play with
the software color temperature adjustment until you matched the
original color from the known source.
