What is generally formed by mixing equal amounts of red and yellow pigments?

Correct answer: Orange

In subtractive pigment mixing, red and yellow are primary colours, and combining them produces the secondary colour orange. Because the quantities are equal, neither colour dominates, so a balanced orange is expected. Option C is correct. Green comes from yellow and blue, violet from red and blue, while brown may result from mixing several colours or from muddy, uneven mixtures.
