>>4448404life isn't actually in color
color happens in post (ie your brain)
there are only waves of {a mysterious medium} vibrating in space at different frequencies (also known as wavelengths since they all travel the same speed ie the speed of light).
The color filters on the photo sites let only waves at certain wavelengths through, producing signals.
There are three signals.
They are combined to produce color images.
If you take three b&w pictures of this dude, each through a different R, G, or B filter, you get the b&w images on the right. If you then project all three images through their corresponding R, G, or B filters onto one spot, you get a color image.
