How will orange appear if a little more yellow is added to the orange made from red and yellow?

Correct answer: A more yellowish orange

The appearance of a mixed pigment depends on the relative proportions of its component colours. Orange begins as a mixture of red and yellow; adding a little more yellow shifts its hue toward yellow while it remains orange. Thus option A, more yellowish orange, is correct. Adding blue would create a different, duller mixture, and the stated change does not directly produce green or violet.
