Low light situation will throw off the white balance of even the best cameras quite easily. Its why camera's have a white balance. I can make blue or orange look white on camera if I balance it to that. A common trick I use in fact is setting the camera to 3200k source and CTB'ing my lamps from 3200k to 4100k (or more simply, using an R60). It gives a nice glow on camera but looks slightly cool to the eye. This is a great example I can give:
Above is a shot of the show I am currently working (Don't worry Jim, I will post some more photos for you
). The stage is lit by four 19 degree 575w Source Four Lekos and two 575w S4 Wide Pars for backlight, all gelled R60. The backround is a bunch of Colorblaze 48s, with the banner in the middle on LED white and the sides lit in a medium blue. The ship on SR has two 10 degree 575w S4 lekos on it. The room and ship looks slightly amber because they are 2800k (room) and 3200k (lekos). My camera thinks the stage is white despite the presenter looking slightly blue to my eyes and the room a lot less amber. The projector looks even more blue because the camera at back of house is absorbing a lot of the LED white (aka slightly blue) from the banner behind it.
The camera was most likely set to auto white balance and kept changing depending on the colors in the picture. That laser, most likely, would have been more pink in hue if you saw it with your own eyes. Note the color at 44s in the video. With the red in the picture, that white looks pale pink/lavender rather then white. Also note the massive setup required to do that and amount of lasers required.
