It is possible to reconstruct coloration after analyzing melanosome structure in the feather. By comparing melanosome in those non-avian dinosaur feather to modern birds melonsomes, it is possible to find out the coloration of the dinosaur feather as melanosomes for each color has distinguish shape. For example, melanosome in this dinosaur feather has similar structure to modern humming bird feather melanosome. As a result, it is likely that the dinosaur had iridescent coloration as the humming bird does, given that the melanosome conserve that similar structure give out similar coloration.
The paper had already displayed the scanning electron microscopic image of the dinosaur feather and compared those SEM imagine of the fossilized melanosome to modern avian dinosaurs such as humming bird.
