Final answer:
Subtractive color refers to pigment mixing where colors are subtracted, as opposed to additive color which involves light color mixing. The concept of Consumptive reading, not commonly referenced in color theory, may involve how content is comprehended based on the reading medium.
Step-by-step explanation:
When discussing Subtractive and Consumptive reading, it likely relates to the way colors are perceived in the context of art and the processes involved in reading and comprehension. Subtractive color refers to the process used with pigments, where color is subtracted when pigments are mixed together, as seen in the subtractive color wheel. Consumptive reading, while not a standard term in color theory, could be interpreted as how one consumes or understands content during reading, which could be influenced by the medium, such as paper or a computer screen.
An example of subtractive color mixing is when mixing yellow and blue pigments to get green. This is different from additive color, which pertains to the way light colors are mixed, as when red and green lights mix to create yellow. With regards to reading comprehension, as described in the article by Mangen, Walgermo, and Bronnick, how text is read (on paper versus on a computer screen) can affect one's understanding and retention of the content.
