Casio projector color issue

My school district this summer received new 13" MacBook Airs. They are running Sierra 10.12.6. In some classrooms, we have Casio XJ-A140V projectors. When we connect the projector, there is a pinkish tint to everything (especially noticeable next to blues). The exact same machine will have no color issues on another projector. We used a MacBook Air we had from last year running an earlier version of Sierra (maybe 10.12.3 or so), and it didn't have a pinkish hue to it. This isn't device specific, as every Air we have connected to the projector with 10.12.6 has had the pinkish hue. We have tried changing settings on the computer, we have tried changing settings on the projector, all to no avail. Does anyone have any ideas?
