A certain wavelength of light lying within the visible spectrum, while being the shortest wavelength. On average, it is about 475 nanometers. Its very near the ultraviolet spectrum, which is bluer than a normal human can see. It is the color of the sky, ocean, and some peoples' eyes. Honestly, I'm hoping only the colorblind are seeing this, cuz otherwise this is kinda dumb.
