Faceplate color hasn't been important to my component selection.
In my music system, I have silver for my Sony SACD player and Pass preamp and mooblocks, blue for McIntosh tuner, grey for Manley phono preamp, and black for Nakamichi cassette player and various external power supplies.
Elsewhere I have a black Magnum Dynalab tuner for which a gold faceplate has been very tempting, tho it would clash with the rest of that system which is black.
