Question

As per the additive colour theory, the mixing of red and green in white light gives which of the following colour wavelength?

• A. Yellow
• B. Magenta
• C. Cyan
• D. Black

Hint:

Remember the acronym RGB for the additive primaries (for light). The combination of the first two, R and G, gives Yellow, which is a primary color in the subtractive (pigment) system.

Answer 1

The Correct Option is A

Step 1: Additive color theory explained. This model shows how light creates color and is used in digital displays. The primary colors are Red, Green, and Blue (RGB).
Step 2: Secondary colors explained. Mixing light in the additive model creates new colors. Combining two primary light colors yields a secondary color.
Step 3: Red and Green combination. Mixing equal intensities of red and green light results in yellow light.The combinations are:

Red + Green = Yellow
Red + Blue = Magenta
Green + Blue = Cyan
Red + Green + Blue = White
