primary subtractive colour for light
A scientist demonstrates a primary subtractive colour for light using colored filters.
Noun: A primary subtractive colour for light is one of the three specific pigment or filter colours (magenta, cyan, and yellow) that are used to absorb (subtract) one of the three primary additive colours of light (red, green, blue) from white light. When combined, these subtractive primaries can be used to create a wide range of other colours.
This is a technical term used in the science of colour, specifically in colour theory, photography, printing, and painting. It describes the fundamental colours used in colour mixing by absorption (subtractive mixing), as opposed to mixing by emission (additive mixing).
- In colour printing, the primary subtractive colours for light—cyan, magenta, and yellow—are used as inks to produce full-colour images.
- To create green using pigments, you mix cyan and yellow, two of the primary subtractive colours for light.
- Understanding the difference between additive and subtractive colour systems requires knowing that the primary subtractive colour for light magenta absorbs green light.
- The concept is central to the CMYK colour model (Cyan, Magenta, Yellow, Key/Black) used in most colour printing processes.
- These colours are called "subtractive for light" because each one (absorbs) a specific primary colour white light. For instance, magenta pigment absorbs green light, reflecting red and blue light, which our eyes perceive as magenta.
- Subtractive primary colour: A more common, shortened synonym.
- Cyan, Magenta, Yellow: The three specific colours that are the primary subtractive colours for light.
- CMYK: The colour model that uses these three colours plus black.
- Primary additive colour for light: The related but opposite concept, referring to red, green, and blue light, which are combined to create colours.
- Subtractive primary
- Process colour (in the context of printing)
- Pigment primary colour
This term has a single, precise scientific meaning. It is not used in everyday conversation but is essential in technical fields involving colour reproduction. Do not confuse it with the traditional "primary colours" (red, yellow, blue) often taught in basic art, which is a less precise, historical model for pigment mixing.
