Actually, our brains perceive the color. Eyes are a sensory organ. When light of various frequencies enters the eyes through the lens and falls on the retina, different chemicals in the retinal cells respond to different properties of the light. Some color sensitive chemicals respond to differences in the red-green frequency shifts, while others respond to differences in the blue-yellow frequency shifts. When these chemical dyes are stimulated by light, the nerve cells that contain them are stimulated and send signals to higher organizations of nerves in the brain that interpret the significance of the color differences. Other nerves in the retina are specialized to respond to dark/light differences; still others respond to movement.

Our eyes perceive color through special cells called cones that are located in the retina. These cones are sensitive to different wavelengths of light, which correspond to different colors. When light enters the eye and stimulates the cones, signals are sent to the brain to interpret the color we see.
The hardest color for the eyes to perceive is believed to be yellow-green, as the human eye is less sensitive to this color compared to others on the spectrum. This can result in difficulty distinguishing various shades of yellow-green.
The retina receives light and contains cells called cones that are responsible for detecting color. The cones are sensitive to different wavelengths of light, allowing us to perceive color.
Color is a physical property of an object that arises from the reflection of light off its surface. It is not a chemical reaction, but rather how our eyes perceive different wavelengths of light interacting with the molecules in the object.
Even in a dark room, there may still be small amounts of light present that can activate the cells in our eyes responsible for detecting color. This residual light can cause us to perceive colors, although they may not be as vibrant as in a well-lit environment.
Objects can be seen by focusing light onto the retina of the eyes, which then sends signals to the brain for processing. The brain interprets these signals to form an image of the object, allowing us to perceive its shape, size, color, and other visual details.
