the colours of the rainbow
in response to Marty's plea about what the exact difference was between blue and indigo, I have been googling the very best scientific websites for the very best images to make it clear.
Blue ranges from a pale turquoise to a decent electric blue, cobalt even!
Indigo appears to be a mixture of blue and Violet, so a kind of purplish tinged blue
Hopefully these images will help!
