Which colour is formed by mixing equal amounts of red and yellow?

Correct answer: Orange

In the traditional subtractive colour model used in basic art education, red and yellow are primary colours, and mixing them produces orange, a secondary colour. Equal amounts generally give a balanced orange, although the exact shade can vary with the pigments used. Therefore option A is correct. Green results from yellow and blue, violet from red and blue, and brown is not the standard answer for this primary-colour pair.
