Question

As per the additive mixing of colours wavelength, the combination of blue and green colours produces which of the following?

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

Hint:

Think of your computer screen (RGB). The secondary colors are the ones you see in your printer ink cartridges (CMY): Cyan (Green + Blue), Magenta (Red + Blue), and Yellow (Red + Green).

Answer 1

The Correct Option is B

Step 1: Understand additive colour mixing. This system applies to mixing light, not pigment. The primary colors of additive light are Red, Green, and Blue (RGB).
Step 2: Recall the combinations of additive primaries.

Red + Green light = Yellow light
Red + Blue light = Magenta light
Blue + Green light = Cyan light
Red + Green + Blue light = White light
Therefore, the combination of blue and green light produces cyan.
