Frequencies, Form, and Color

The following youtube video is wonderful, for those of us who love discovering the mysterious secrets of our world. After watching, I was remembering my experience at a former place of work, where we created holograms by using a laser to cut the media at particular angles. Which angle determined the color of the hologram. I don't know the angles, but I can't help but wonder if they correspond to the frequencies and geometric numbers found in the video below. Because, if they are then we not only have the expression of these frequencies in music, but in color as well. :)
