Chapter 28, Problem 14A

To determine

To discuss the process of mixing of pigments called subtraction instead of addition.

Explanation of Solution

Introduction:

There are two types of color mixing. They are additive color mixing and subtractive color mixing. The process of producing a color by mixing pigments is called subtractive mixing. 

The additive color mixing is the process of creating a new color by adding the set of wavelengths to another set of wavelengths, so, lights of different wavelengths are mixed. It is called additive color mixing because all the wavelengths reach the human eye.

The subtractive color mixing is a process of forming new colors by the removal of wavelengths from light with a spectrum of wavelengths. When pigments are mixed the wavelengths are deleted from what the human eye can see because each pigment will absorb some wavelength that the other paint reflects.

Thus, subtractive color mixing occurs when mixing pigments or color materials.

Conclusion:

The subtractive color mixing is the process of deleting the wavelengths of pigments.
