I have a science question about electromagnetic spectrum..please help?

The electromagnetic spectrum is made up of all 7 primary colours. The amount of magneticness each colour has is related directly to how near to black it is (black being the most magneticness and white being the least magneticnessless). That is why the top of a rainbow (Red) is less magnetic than the bottom (blue) and explains why the end of rainbows point downwards towards the land rather than upwards towards the sky. Interestingly, if there were rainbows on the moon or the other planets (which there are not) things would be very different because of gravity.
