Project 41 - the eye's sensitivity to colour

I was perhaps over-excited about doing this exercise but there is something very satisfying about seeing colours arranged to make another image of their own. Unfortunately it transpired that I didn't have many orange images, nor indigo. However, with what I had and the use of the Rotate tool, I have created a semblance of the curve required in project 41 - the curve of the eye's sensitivity to colour.
