Color depth triangle does enclose a much larger gamut, so whether more than three primaries results in a difference to the human eye is not yet proven, since humans are primarily trichromats, though tetrachromats exist. Color depth Color depth or colour depth (see spelling differences), also known as bit depth, is either the number of bits used to indicate the color of a single pixel, in a bitmapped image or video framebuffer, or the number of bits used for each color component of a single pixel. For consumer video standards, such as High Efficiency Video Coding (H.265), the bit depth specifies the
Canadian Association for Physical Anthropology mission statement of CAPA/ACAP, as listed on the website, is as follows: "The Canadian Association of Physical Anthropology / L'Association Canadienne D'Anthropologie Physique is a learned society of international scholars and students whose aim is to promote and increase awareness and understanding of physical (biological) anthropology among its membership, as well as to supporting institutions and agencies and the public at large.
