Yup - they've lost ALL their green - they're all purple. Seriously, take the photos under natural light or turn your lights up to 100% when taking the shot...
I've looked at what you've given us and I can see some lighter markings on the leaves (what color it is, unfortunately, is a mystery) but the pattern of markings do not indicate a bug of any sort... more mutant than anything...
Sorry - and good luck!
