Final answer:
The query '0.6R - 0.28G - 0.32B' refers to the RGB color code, specifically used in computer and television display technologies that blend red, green, and blue light to produce varied colors on the screen.
Step-by-step explanation:
The student's question 0.6R - 0.28G - 0.32B is regarding the concept of RGB color code used in display technologies such as computer monitors and televisions. When looking at a device screen with a magnifying glass, individual pixels can be seen changing colors through the variation of light intensity for red, green, and blue subpixels. RGB color television and computer displays create the spectrum of colors we see on-screen by this method.
Primary colors such as red, blue, and yellow are fundamental because they cannot be created by mixing other colors, and all other colors derive from them. For RGB displays, red, green, and blue serve as the primary colors used in color mixing. The wavelengths and frequencies corresponding to red, green, and blue light dictate the color that is perceived, derived from visible light's spectrum.
