  The Jupiter Trojan asteroid 128383 (2004 JW52) was recently reported to have
optical colors that are incongruous with its dynamical class. New and archival
observations show that this is not the case. This is a reminder that we must
always rule out the possibility that the Point Spread Function (PSF) of a minor
planet is blended with that of a background sidereal source in survey images
before its colors in the associated survey catalog can be considered reliable.
