Step 1: Understanding Colour Mixing.
When mixing red and green, the resulting colour can be considered a brownish tone in subtractive colour mixing (such as mixing paint). This happens because red and green are not complementary colours, and their mixture creates a muddier, more neutral colour like brown. In the additive colour mixing system (such as with light), mixing red and green gives yellow, but in pigment mixing, the result is brown.
Step 2: Evaluating the Options.
- Option (1): Yellow is produced by mixing red and green in the additive system, but not in pigment mixing.
- Option (2): Orange is formed by mixing red and yellow, not red and green.
- Option (3): Brown is the correct result of mixing red and green in pigment mixing, creating a neutral colour.
- Option (4): Violet is produced by mixing red and blue, not red and green.
Conclusion:
Therefore, the correct answer is (3) Brown.
