What is the correct sequence from red toward yellow on a twelve-part colour wheel?

Correct answer: Red then red-orange then orange then yellow-orange then yellow

The governing concept is the ordered progression of hues on a twelve-part colour wheel. Moving from red toward yellow passes through the intermediate tertiary hue red-orange, then the secondary hue orange, then the tertiary hue yellow-orange, and finally yellow. Thus option A gives the complete adjacent sequence. The other choices skip intermediate hues, reverse relationships, or list colours that are not located along this route.
