Human eyes are sensitive to the red, green, and blue colors of the electromagnetic spectrum.

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that human eyes are sensitive to the red, green, and blue colors of the electromagnetic spectrum?

Yes. Human color vision is trichromatic, relying on three classes of cone photoreceptors in the retina sensitive to the long (red), middle (green), and short (blue) wavelength regions of the visible spectrum.
