There are more colors in a rainbow than there are stars in the Universe …

Great article on how frequency and our anatomy affects what we can see
– we can only see a subset of the wavelengths that light appears in
– in that limited range, how many frequencies are available to us?
– light is quantum – finite and discrete – meaning that it’s waves and frequencies must be the same
– however the sun’s plasma gives off so many frequencies that they become (in effect) continuos
– the eye is restricted in what it can perceive, most people have 3 sets of cones, with 100 cells each. Each cell is sensitive to 1 shade, meaning you can see approximately 100(3) or 1,000,000 colors
