| Definition: | a specification of a colour stimulus in terms of operationally defined values, such as three tristimulus values
NOTE 1 – When the meaning is clear from the context the term colour can be used alone.
NOTE 2 – In German, "Farbe" is often used instead of "Farbempfindung". The use of "Farbe" in the sense of "Farbvalenz" should be avoided. It is only when the sense is obvious from the context, or when "Farbempfindung" and "Farbvalenz" are equally suitable, that "Farbe" may be used in the sense of "Farbvalenz".
