So I have three of the same projector and one isn't matching up color wise (or gray scale for that matter). All the settings are exactly the same. I even did a factory reset just to make sure. I attached attached a photo of a gray scale. The middle projector images look gray and the outer ones look brown. Any ideas

You need a colorimeter and a fair bit of training and a good deal of luck to color match projectors.

The lamps are the issue here. Lamps come off the assembly line and they have different color characteristics. Some glow brighter, some not so much. The lamps themselves are not color matched, so you have to adjust settings on the projector to deal with this greyscale shift.

You likely don't have the tools you need for this, so a calibration disc may help some, but realistically, it is by eyesight that you guess your way through.

There are other solutions to this out there, but I can't think of what they are right now - They tend to start at several hundred dollars.

In a critical setup, this is money well spent, because not only do lamps look different out of the box, they also age differently and once it is setup perfectly the first time, after a month of use, it will drift and no longer match up.

This is the joy of multiple projector setups and IMO, is one of the single biggest commitments anyone can make when it comes to projection.

Actually the outer images look more of a gray scale than the center one to me, and it's far easier to tweak one than two.

If it were me in your place I would call in someone able to color balance with decent tools. If you were to try it yourself you will likely cause it to shift even further.
