The rainbow, according to the most popular view, contains 7 colors: red, orange, yellow, green, blue, indigo, and violet.

A color table will be of help here. It can be one of the tables found on the Internet, such as rapidtables.com. The table shows the color itself, its name, the hexadecimal code of color, as well as the decimal code.
This—the decimal code or RGB code—is necessary to accurately colour the relevant rainbow color sector.
Take a note of these codes and now we can enter them thus assigning a color to each sector—and the real rainbow circle is ready!
On the next slide, we'll create an organization chart, SmartArt, which will accurately display all seven rainbow color tones.
At the beginning, after insertion, all SmartArt graphics circle sectors are in the same color. It is necessary to color each of the seven sectors in the appropriate color. When choosing colors from the menu palette or the standard, we cannot be sure that the color really matches the color of the rainbow.
