This beautiful gif, named Lights
, from Bees&Bombs
, aka David Whyte
and Brian Fitzpatrick
), it made me remind of a little discussion between two elementary school teachers.
The first claimed that the primary colors are red, green, and blue
, while the second claimed that they are cyan, magenta, and yellow
Who among the two teachers was right? Both teachers!
In fact red, green, and blue are the primary colors used in the additive color mixing
, while cyan, magenta, and yellow are used as primary colors in the subtractive color mixing
The behavior of light mixtures (additive color mixing) is different from the behavior of paint or ink or dye or pigment mixtures (subtractive color mixing) because the perception of light by the eye follows different rules by the absorption of light by material substances.
The things are not so simple. Maybe we will deepen in a future post.
In any case, the primary colors are not a fundamental property of light but are related to the physiological response of the eye to light. Readings for further information
