Although I know vaguely that combining red, green and blue lights results in white lights, it still mind blowing to see that in action. It is also very counter intuitive because as a kid, I mixed yellow and blue color pigments to get green(subtrative colors). Here, mixing red light and green light gets yellow!(additive colors)

If mix red, green and blue pigments, you will get black in the end. But if you mix R,G,B *lights*, you will get white light.
I came across this when I was looking for ways to produce warm white/yellowish LED light that does not have even a tiny bit of blue spectrum that normal warm white LED lights have.

I am going to buy red, blue and green LED lights to actually try this out!
