Which intermediate colour is obtained when blue is dominant in a blue and yellow mixture?

Correct answer: Blue-green

The governing concept is subtractive colour mixing in a traditional pigment context. Blue and yellow combine to produce green; when blue is used in the greater proportion, the resulting hue shifts toward blue while remaining between the two parent colours. Therefore option C, blue-green, is correct. Equal proportions would give a more neutral green, yellow dominance would move toward yellow-green, and blue-violet requires blue mixed with violet or red, not yellow.
