If you are serious about doing this right then a 2D CCD sensor and a prism hires grating combo at right angles will allow you to quantify the entire visible spectrum at ultra high resolution. Be careful though Perkin-Elmer (and others) have some very good lock out patents on this trick (may be about to expire).
Again, not looking to make an "instrument". The phone idea may work
if the CCDs don't freak out with high intensity sources.
CCDs are almost indestructible unless you point them at the sun. Even then they handle it much better than a human eye. Webcams are probably a lot cheaper though. If you find one of the paint firm's colour matching apps and test chart it may already do what you want or close enough.
