Thank you very much for all your troubleshooting. After looking at the link that you gave me, it looks like the problem is my monitor. I am using an HP laptop, and I guess the screen is just not up to par. I guess I will just have to invest in a nice desktop monitor, and hopefully that will be the end to the purple problem.
thanks again.
Just check first to ensure that you are using the same colour spaces in all applications. If you are using adobe 1998 rgb in PS with the monitor calibrated to srgb you will find a red hue.
