Step 1: Understanding Colour Mixing.
When mixing two primary colours, yellow and blue, a secondary colour is created. Yellow and blue are both primary colours in traditional colour theory. When combined, they produce green. This is because blue and yellow light combine to form green in the subtractive colour mixing model used for paints.
Step 2: Evaluating the Options.
- Option (1): Mixing yellow and blue does not produce brown.
- Option (2): Mixing yellow and blue creates green, which is the secondary colour formed.
- Option (3): Orange is created by mixing red and yellow, not yellow and blue.
- Option (4): Violet is created by mixing red and blue, not yellow and blue.
Conclusion:
Therefore, the correct answer is (2) Green.
