Colour which are made by mixing a primary colour with a secondary colour is called :

Question

Accepted Answer

The correct answer to the question is Option 3: Tertiary colour.

1. **Explanation for Option 3 (Tertiary colour):**
   - Tertiary colours are created by mixing a primary colour with a secondary colour. Primary colours are red, blue, and yellow, while secondary colours are green, orange, and purple, which are formed by mixing two primary colours. When you mix a primary colour with a secondary colour, you get a tertiary colour. For example, mixing blue (a primary colour) with green (a secondary colour) results in blue-green, a tertiary colour. This is why Option 3 is the correct answer.

2. **Explanation for why other options are incorrect:**

- **Option 1 (Mixture of two colours):**
     - While a tertiary colour is indeed a mixture of two colours, this option is too vague and does not specifically refer to the concept of tertiary colours. The term "mixture of two colours" could apply to any combination of colours, not just the specific combination of a primary and a secondary colour that defines a tertiary colour.

- **Option 2 (Main colour):**
     - The term "main colour" is not a standard term in colour theory. It does not accurately describe the result of mixing a primary colour with a secondary colour. Primary colours are sometimes referred to as "main colours," but they are not created by mixing other colours.

- **Option 4 (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. Complementary colours are opposite each other on the colour wheel, such as red and green or blue and orange. They are not created by mixing a primary colour with a secondary colour, so this option is incorrect in the context of the question.

In conclusion, Option 3 is the correct answer because it accurately describes the result of mixing a primary colour with a secondary colour, which is known as a tertiary colour.
