Which mixture is suitable for making a yellow-dominant orange?

Correct answer: More yellow and less red

Orange is created by mixing the primary pigments red and yellow. To make the resulting orange appear yellow-dominant, yellow must be present in a greater amount than red; therefore, option B is correct. More red would produce red-orange. Blue is not one of the components of orange, and equal blue and yellow would normally produce green rather than orange. The key principle is that the larger component influences the colour bias.
