Which is the complementary colour of Blue ?

Question

Accepted Answer

The complementary color of blue is orange, which is why Option 4 is the correct answer. Complementary colors are pairs of colors that, when combined, cancel each other out. This means they produce a grayscale color like white or black when combined. When placed next to each other, they create the strongest contrast and reinforce each other.

1. **Explanation for Option 4 (Orange):**
   - In the color wheel, complementary colors are located directly opposite each other. Blue and orange are opposite each other on the color wheel, making them complementary. This relationship is based on the principles of color theory, where complementary colors enhance each other's intensity and vibrancy when placed side by side. This is why orange is considered the complementary color of blue.

2. **Explanation for why other options are incorrect:**
   - **Option 1 (Yellow):** Yellow is not the complementary color of blue. Instead, yellow is complementary to purple. On the color wheel, yellow and purple are directly opposite each other, which is why they are considered complementary.
   - **Option 2 (Red):** Red is not the complementary color of blue. Red is complementary to green. These two colors are opposite each other on the color wheel, making them complementary.
   - **Option 3 (Green):** Green is not the complementary color of blue. Green is complementary to red, as mentioned above. Blue and green are adjacent on the color wheel, which means they are analogous colors, not complementary.

In conclusion, based on the principles of color theory and the arrangement of colors on the color wheel, orange is the complementary color of blue, which justifies why Option 4 is the correct answer.
