When two colors on the color wheel are directly across from each other and share no common colors, they are known as complementary colors. Complementary colors are opposite each other and create a high contrast when placed together.

To find the two colors that fit this description, you can refer to a color wheel. There are different variations of color wheels, but the most commonly used one is the RYB (Red, Yellow, Blue) color wheel.

Start by locating a specific color on the color wheel. For example, if you choose the color blue, you would then identify its direct opposite on the wheel. In this case, the opposite of blue is orange. Blue and orange are complementary colors.

Similarly, if you choose another color, such as red, its direct opposite on the color wheel would be green. Red and green are another example of complementary colors.

Therefore, the two colors that are directly across from each other on the color wheel and share no common colors are:

- Blue and Orange
- Red and Green
