actually, I can notice the color difference through the camera. Just saying.
Ah okay wasn't sure if my phone's camera quality could quite pick up the discrepancy. Also I use Movie Maker to edit these videos so it lowers the resolution down to about 480p so it looks like garbage so I just assumed while shooting that most people would not be able to pick up the color discrepancy.
But in live conditions you can bet your bottom dollar a spectator will notice if you leave it out for too long. You will have to cover it really well for them not to notice. I'll probably only perform this when my friends are drunk and less observant of such flaws.
But the color discrepancy isn't even the worst part....in fact I can't even really say what it is due to exposing the entire gimmick. A hint is that there is this obnoxious glare across the card and if that glare occurs in real life, a spectator for sure will figure this effect out and have a good laugh at how silly it is.
