When the projector is switched on with the visualiser the light on the wall screen from the projector is yellowy/green instead of the usual white light on the screen, this can alternate several times...
Generally speaking, if you have discoloration that changes during use, you will find that it's due to one or more of your cables either not being connected properly or being damaged.
The first thing I need to ask is whether or not you have this same discoloration when the projector is not connected to anything. If so, the problem is internal and I can't really help there except to tell you to contact a technician.
However, if the image color is fine when the projector is not connected to anything, the problem is definitely a cable or connection issue. That being said, try the following steps:
1) Check all your connections and make sure everything is firmly connected. Discoloration can occur from your cables only making partial contact. Also, while you do this, observe the ends of the cables themselves to make sure they are undamaged.
2) Flex your cables, starting at one end and moving slowly to the other. If you have a damaged wire, the image should change color/flicker/or even disappear entirely when you reach the damaged portion.
3) If that did not work, replace your cabling with a spare. If that solves your problem, then the old cable is damaged/defective and should be disposed of.
4) Normally, I would tell you to also check the settings in the menu as well, but if the image changes color during use, it's not a settings issue.
I hope that helps.
