Hmm... That could be possible.
e.rose, I was indeed talking about a blank layer in which you apply the image.
If this does not help the color space might actually be a good thing to look at.
Just check the Image>Mode menu to see what it is at (RGB, CMYK, LAB, etc). If it's not at RGB try setting it to RGB and see if that changes the image in the same way... If so: There's your problem.
Ps. You can upload psd files to file upload sites, not sure which ones are popular nowadays but there should be loads of them around (I think mediafire is one?). Uploading a public file to dropbox would work too.
