Did shutter speed affect this?

Not in any way I can think of.
Yes, it would. Its really the same thing that we are talking about above, just from a different perspective. If you had a light flashing green for 1 second and red for 1 second, you would probably get a yellow image if you shot it with a 2 second exposure. Shoot it at 1 second and you could see red or green or maybe even yellow if you caught half of each cycle. Speed that flashing up to 100 cycles per second and your eyes would see yellow and then we would be talking about the same situation as above. Our eyes just see a yellow light, shoot it at 1/100 or slower and you should get a yellow image just as you saw it. Shoot it faster than 1/100 second and you will start wondering why your picture is so red or green instead of yellow and its never exactly the same. That faster speed does not allow you to catch a full cycle and you don't get an even mix of colors. It is just high speed photography capturing the components of modern man-made light shining at us.
No because the colors add up making the light whiter. It's when the shutter speed is faster than you get let's say a side yellower than the other to a weird color cast that is just part of the picture.
Few things occurred to me:
1) Some projectors have color wheels that spin in the path of the light to create the color. My grasp is the fastest ones turn at 14,400 RPM or 240 revs per second, so any faster shutter speed would freeze the wheel. Older projectors spin slower and would be equivalent to 60 or 120 revs per second. All this on the edge of my grey matter.
2) Regardless of color temperature the video was recording, the color temperature of images recorded during projection would be that of the projector's lamp. Fairly certain of this one.
I should probably add some sort of signature.
