MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Primary colors include red, blue and yellow. Primary colors cannot be mixed from other colors. They are the source of all other colors. Secondary colors are mixed from two primary colors adjacent to each other on the color wheel.

Detailed explanation-2: -There are three commonly used primary colour models: RGB (red, green, and blue), CMY (cyan, magenta, and yellow), and RYB (red, yellow, and blue). The colour variations between the models are due to the differences between additive and subtractive colour mixing.

Detailed explanation-3: -The four primary colors in the 4-primary color wheel are blue, yellow, green and red. This differs from the color mixing wheel, which only has three primary colors.

Detailed explanation-4: -Robert Boyle, the Irish chemist, introduced the term primary color in English in 1664 and claimed that there were five primary colors (white, black, red, yellow, and blue).

Detailed explanation-5: -RYB misses vast ranges of hues and values; especially violets, bright greens, and blue-greens. Opposite colors in CYM cancel each other out to create black, and in RGB, the primaries combine to create a pure white. Equal amounts of three CYM/RGB colors create very pure grays, almost impossible to create in RYB.
