Pink glitter collected by the DMSE&R.
While not quite as vile a color as urple or other Suvian colors, pink, a lightish red to purple hue, is often considered a Sue color, and hated, because of its sheer pinkness.
This, however, might just be due to the fact that if an agent is especially blood-covered from a mission, and they forget to use bleach for their whites when they do their laundry, they end up with a large amount of pink clothing to go with their black uniform. The glitter many Suvians have in addition to or instead of blood is often pink.
