Which proportion is suitable for making a yellow-dominant green?

Correct answer: More yellow and less blue

The governing concept is colour mixing by proportion. Yellow and blue combine to produce green, but the colour that is present in the larger amount determines the visible bias. Therefore, using more yellow and less blue produces a green that shifts toward yellow. Equal quantities give a more balanced green, while more blue gives a blue-dominant green. Red is not part of this two-colour mixture.
