Colors
The first four discovered Neptune trojans have similar colors. They are modestly red, slightly redder than the gray Kuiper belt objects, but not as extremely red as the high-perihelion cold classical Kuiper belt objects. This is similar to the colors of the blue lobe of the centaur color distribution, the Jupiter Trojans, the irregular satellites of the gas giants, and possibly the comets, which is consistent with a similar origin of these populations of small Solar System bodies.
The Neptune trojans are too faint to efficiently observe spectroscopically with current technology, which means that a large variety of surface compositions are compatible with the observed colors.

Famous quotes containing the word colors:
“Hoot how the inhuman colors fell
Into place beside her, where she was,
Like human conciliations, more like
A profounder reconciling, an act,
An affirmation free from doubt.”

“Few colors last; with their eternal thirst, time and light suck on them, and they bleach the black doctor’s hat until it’s grey like a dunce’s cap.”
—Franz Grillparzer (1791–1872)
“I can add colors to the chameleon,
Change shapes with Proteus for advantages,
And set the murderous Machiavel to school.”
