What are the seven colors associated with visible light?

ROY G. BIV is the acronym that represents all of the colors in the visible spectrum of light. R (red) - O (orange) - Y (yellow) - G (green) - B (blue) - I (indigo) - V (violet). Not only are those the colors we can see as humans, but they are also in the right order. Red has the longest wavelength and violet has the shortest.
