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
Philosophy of color Philosophy of color Within the philosophy of color, there is a dispute between color realism, the view that colors are physical properties that objects possess, and color fictionalism, a species of error theory viewing colors according to which there are no such physical properties that objects possess. One of the topics in the philosophy of color is the problem of the ontology of color. The questions comprising this field of research are, for example, what kind of properties colors are (i.e. are they physical properties of objects? Or are they properties of their own kind?), but also problems about the
