  With the rapid advancement of technology, the design of virtual humans has
led to a very realistic user experience, such as in movies, video games, and
simulations. As a result, virtual humans are becoming increasingly similar to
real humans. However, following the Uncanny Valley (UV) theory, users tend to
feel discomfort when watching entities with anthropomorphic traits that differ
from real humans. This phenomenon is related to social identity theory, where
the observer looks for something familiar. In Computer Graphics (CG),
techniques used to create virtual humans with dark skin tones often rely on
approaches initially developed for rendering characters with white skin tones.
Furthermore, most CG characters portrayed in various media, including movies
and games, predominantly exhibit white skin tones. Consequently, it is
pertinent to explore people's perceptions regarding different groups of virtual
humans. Thus, this paper aims to examine and evaluate the human perception of
CG characters from different media, comparing two types of skin colors. The
findings indicate that individuals felt more comfortable and perceived less
realism when watching characters with dark colored skin than those with white
colored skin. Our central hypothesis is that dark colored characters, rendered
with classical developed algorithms, are considered more cartoon than realistic
and placed on the left of the Valley in the UV chart.
