Colors in the representation of biological structures.

Among the many properties of proteins, sugars, nucleic acids, membranes and other cellular components, color is not present.

In this article, I suggest how we can conciliate these two situations, with the contribution of biologists, artists, and computer graphics and perception experts. The concept can be developed in a series of initiatives involving the community, including discussion sessions, technical challenges, experimental studies and outreach activities.
