It's effectively your brain doing automatic white balance, it sees everything being tinted cyan so it just sorta subtracts cyan from the area, which results in white being reddish

you can do this physically (by tiring out the colour-sensing cells in your eyes) if you stare at a colour for about 30 seconds then quickly look at a white surface, you should see the inverse of the first colour.
