Mixture of two primary colours is known as:

Question

Accepted Answer

The correct answer to the question "Mixture of two primary colours is known as:" is Option 2: Secondary colour.

1. **Explanation for Option 2 (Secondary colour):**
   - Primary colours are the basic colours that cannot be created by mixing other colours. In the traditional colour wheel, the primary colours are red, blue, and yellow. When two primary colours are mixed together, they form what is known as a secondary colour. Specifically, mixing red and blue gives purple, blue and yellow give green, and yellow and red give orange. These resulting colours are termed secondary because they are derived from the combination of two primary colours.

2. **Explanation for why other options are incorrect:**
   - **Option 1 (Complementary colour):** Complementary colours are pairs of colours that, when combined, cancel each other out. This means they produce a grayscale colour like white or black. They are located opposite each other on the colour wheel, such as red and green or blue and orange. Complementary colours are not formed by mixing two primary colours.
   - **Option 3 (Opposite colour):** This term is not commonly used in colour theory. While it might imply a relationship similar to complementary colours, it does not specifically refer to the result of mixing two primary colours.
   - **Option 4 (Analogous colour):** Analogous colours are groups of three colours that are next to each other on the colour wheel, sharing a common hue. For example, red, red-orange, and orange are analogous colours. They are not formed by mixing two primary colours but rather are used together to create harmonious designs.

In conclusion, the mixture of two primary colours results in a secondary colour, which is why Option 2 is the correct answer.
