The dinosaur also showed countershading
patterns, in which the top part of the animal is darker-colored and the bottom is lighter.
The researchers came to that conclusion based on studies of the dinosaur's skin, showing that Borealopelta exhibited countershading
, a common form of camouflage in which an animal's underside is lighter than its back.
If it is a bright day, a bright color such as blue and white mimics the natural countershading
of a baitfish.
From Abbott Thayer to the present day: what have we learned about the function of countershading
Humans have higher visual acuity within the achromatic channel: this explains why JPEGs are still visually legible after image-file compression, and how artists direct the gaze and influence our perception of value in the achromatic channel through techniques such as countershading
. Berns suggests that for the purposes of a conservator; matching the chromatic content is less important than matching the achromatic content of an area when carrying out imitative inpainting.
That type of coloring, called countershading
, shows up in animals from penguins to fish and may act as a form of camouflage.
Psittacosaurus was mainly brown but with a paler underside of the tail and belly, a pattern called countershading
that may have helped the 1.5-metrebipedal plant-eater go unnoticed by hungry predators, the scientists said on Thursday.
The dorsal and ventral colors are subtly delimited with weak countershading
(Supplementary Material S4).
This is achieved either through crypsis--the process of blending with a background through methods including countershading
and disruptive patterning--or mimicry which allows an object to stand out but in disguise.
In addition, the statocyst is necessary for proper vestibular function, such as the countershading
reflex, dorsal light reflex, and compensatory counter rolling of the eyes.
Some have pearlescent blue or black countershading
. A baitfish falling out of its school is losing its color.
A dark strip at the top and a white splash underneath disrupt our expectations of how an object will appear (countershading
