Sometimes the adjustment to keep neutrals neutral is called ''white balance'', and the phrase ''color balance'' refers to the adjustment that in addition makes other colors in a displayed image appear to have the same general appearance as the colors in an original scene.<ref>{{Cite book| title = Introduction to Color Imaging Science | url = https://archive.org/details/introductiontoco00leeh_034 | url-access = limited | author = Hsien-Che Lee | publisher = Cambridge University Press | year = 2005 | isbn = 978-0-521-84388-1 | page=[https://archive.org/details/introductiontoco00leeh_034/page/n471 450] }}</ref> It is particularly important that neutral (gray, neutral, white) colors in a scene appear neutral in the reproduction.<ref>[http://www.nikondigital.org/articles/white_balance.htm White Balance].

===Psychological color balance===
Humans relate to [[Human skin color|flesh tones]] more critically than other colors. Trees, grass and sky can all be off without concern, but if human flesh tones are 'off' then the human subject can look sick or dead. To address this critical color balance issue, the tri-color primaries themselves are formulated to ''not'' balance as a true neutral color. The purpose of this color primary imbalance is to more faithfully reproduce the flesh tones through the entire brightness range.
