Understanding the arithmetic of color

Received 13 January 2015; accepted 26 January 2015In this work we propose to introduce Arithmetic for the Mixture of Colors, which can be defined from dividing the electromagnetic spectrumof white light in three thirds, and by associating each of them to an algebraic expression of the three primary additive and subtractive colors.Then, we will give the rules for adding or subtracting to predict the new mixture of resultant colors.Keywords: Mixture of colors; chromatic arithmetic.PACS: 01.40.E, 01.40.eg, 01.40ek
