What does subtractive mean?
Subtractive is an adjective describing a process or result that involves removing or subtracting elements. Its best-known use is in color theory: subtractive color or pigment mixing creates colors by absorbing selected wavelengths of light, as opposed to additive mixing, which combines emitted light. The word is also used in technical descriptions of printing, photography, synthesis, and chemistry when a material, image, or component is produced by removing something from a larger whole. In general English, subtractive can imply reduction, loss, or subtraction, though it is more formal and less common than words such as deductive or diminishing. The distinction between subtractive and additive processes is central in understanding how printed colors, projected images, and photographic images are formed. The word is especially useful in technical writing because it identifies methods based on removal rather than addition.
adjectiveInvolving subtraction or the removal of elements from something. In color and photographic processes, it describes the production of an image or color by subtracting or absorbing selected wavelengths of light.
- Involving subtraction or removal.
- Relating to or using a process in which colors or images are produced by removing selected wavelengths of light.
"The printer uses a subtractive process to reproduce colors on paper."
"Subtractive mixing of pigments can produce a wider range of colors than mixing light."
"The chemist regarded the reaction as a subtractive change in which one component was removed."
Subtractive color works like a filter: removing selected wavelengths of light can leave the color you see.

Where does subtractive come from?
Subtractive derives from Latin subtrahere, meaning 'to draw away' or 'to subtract,' formed from sub- 'under' and trahere 'to draw, pull.' The English word entered through the mathematical root and later became especially common in technical descriptions of color and image formation. Subtraction and subtrahend are related words sharing the same Latin foundation.
How subtractive is actually used
The term is especially common in technical discussions of color, printing, photography, and image formation. In general contexts, it can mean reducing or removing something, but it is less common than 'subtractive' in the sense of subtraction.
