Final answer:
On a traditional color wheel, the color yellow should be on the bottom-right tip of the triangle, with red at the top and blue to the left.
Step-by-step explanation:
To create a color wheel, the color that should be on the bottom-right tip of the triangle is yellow. The primary colors are red, blue, and yellow. These colors are found equidistant from each other on the color wheel. They are the foundational colors, not produced by mixing other colors, and all other colors on the wheel are derived from various combinations of these three. Since color wheels typically have three primary colors spaced equally apart, and given the traditional arrangement, where red is often at the top, blue is to the left, placing yellow naturally falls to the bottom-right tip.
