Which mixture can produce a reddish orange?

Correct answer: More red and less yellow

Orange is formed by mixing red and yellow. To shift orange toward red, the mixture must contain more red and less yellow, so option A is correct. Equal quantities normally give a balanced orange. More yellow would create a yellowish orange, while adding blue introduces a third primary colour and may dull or brown the mixture rather than producing a clear reddish orange. The governing idea is that the larger component influences the resulting hue more strongly.
