blue to red appears as red to blue - why?

It may be the orientation of the camera. If you are using the JDEPC-0V05 as currently shipped with PLAB Spectrometer 3.0 the usb connector should be at the top.

This could be a few things, but the simplest is that you built a spectrometer with the camera rotated 180 degrees from the way it should be in the standard PL kits. Can you rotate your spectra?

Also, if you can link to them, we can take a closer look!
