Your eye has cones and rods that are stimulated by light.

White
the cones which sence colour are concentrated near the center of the retina. when looking straight at an object it maxmizes the number of cones being stimulated. Alice rocks!!!!!!!!!!!!!!!!!!!!
trichromatic theory
I do not remember the exact science of it, but it has to do with the photo receptors in your eyes. There are two kinds of receptors in your eyes: cones which focus on color and rods, which focus on light. There are 3 kinds of cones: those that see blue, green or red (i.e. short wavelengths, medium and long.) When more than one wavelength reaches the cones (say a medium one (green) and a long one (red)) then the cones that receive these two wavelengths (i.e. the red and the green cones) cancel each other out and the Blue receptor is stimulated instead.The blue cone can see either blue or yellow. If it receives a short wave, it sees blue, but if the green and red cones are stimulated at the same time (remember they cancel each other out), then the blue cone is stimulated to see YELLOW.
trichromatic theory
No.
They are missing one type of cone, not all the of the three types of cones.
The organ of vision is the retina of the eye. The sensory receptors are called photoreceptors. When photoreceptors are stimulated, impulses travel within the optic nerve (CN II) to the visual (occipital) cortex of the brain for interpretation. There are two types of photoreceptors: Cones are photoreceptors for color vision and produce sharp images while the Rods are photoreceptors for night vision and produce silhouettes of images.
Cones?
Smart snacks rainbow coloured cones are not cones to be eaten with ice cream. They are actually educational toys. They are available on Amazon for decent prices.
