I always learned “ROYGBIV” as the colors of the rainbow. Red, orange, yellow, blue, indigo, violet.

What’s up with the last two? Isn’t indigo basically just dark blue? Why is it violet and not purple? Can’t it just be “ROYGBP”?

    Indigo is closer to Blue. Violet is closer to Red.

    Purple is inbetween Indigo and Violet.

        Indigo color is created by mixing more parts of Blue than Red.

        Violet color is created by mixing more parts of Red than Blue.

        Purple is created when two wavelengths are visible at the same time, between Red and Blue. At the same time, Violet colors border on Red, and Indigo colors border on blue.

        Therefore, Purple is a color inbetween Violet and Indigo.
