One of the colors of the rainbow, indigo—a dark purplish blue—gets it name from the indigo plant used to create the indigo dye. - Jacci Howard Bear's Desktop Publishing Colors and Color Meanings

Indigo appears between blue and violet in a rainbow. Purple grapes and blueberries are indigo. The deep blue of dark denim blue jeans is indigo. 

Indigo is a cool color that carries the blue symbolism associated with the dark shades of blue.

Indigo conveys trust, truthfulness, and stability. It also borrows some of the authority and royalty of purple, as indigo was once considered a royal blue.​
