1. Orange and blue
2. White and black
3. Yellow and blue
4. Red and green

Answer 1

Correct Answer - Option 4 : Red and green

The correct answer is Red and green.

• The Red and green combination of color is the most convenient during the day and night time.

• The modern color theory is also known as the RGB color model which is red, green, and blue are additive primary colors.
• A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light.
• When we look towards the sun at sunset, we see red and orange colors because the blue light has been scattered out and away from the line of sight.
• Blue, Red, and green, light combined together make white light, and these three colors, combined in different mixtures, can produce almost any color.
• This is the principle used to make the colors on television and computer screens.
