3 February 2008 UTC I think you re going overboard with your original research claim here Specifically from our article on OR The purpose of the original research is to produce new knowledge rather than to present the existing knowledge in a new form e g summarized or classified The concepts I present with the color Venn diagram are not new AND OR XOR I am simply presenting existing knowledge in a new form classsified by color and not even all that new as there are numerous color Venn diagrams out there including this one using rectangles I still find colored and striped Venn diagrams more cheerful and welcoming than black and white or even shades of grey BTW I did a print of my Venn diagram and it still works in greyscale as the intersection prints out with darker grey than the rest of the shaded area Therefore the stripes don t even seem necessary to overcome the greyscale printing and colorblind viewer complaints I will now update my caption to indicate this 14 36
