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

After his death, the journal continued as the organ of the American Association of Physical Anthropologists, which Hrdlička had founded in 1930.

In 2009, the journal was selected by the Special Libraries Association as one of the top 10 most influential journals of the century in the fields
