Seeing colors of light is a blessing. Light is electromagnetic energy vibrating in a specific range of frequencies, but our brain perceives the frequencies as colors.
When your retina receives a particular frequency of electromagnetic energy, it sends a signal to the visual part of the brain, which generates a mental image with luminosity and what we call color. Seeing colors is merely our perception of the various frequencies or wavelengths of light energy.
Every creature with vision can see different intensities of light, but not all can see as many colors as humans can. However, some, such as bees and butterflies, can see colors we can’t see. Human eyes see best in the range of frequencies that our brain interprets as green, but our vision is not as sensitive in the red and blue frequencies. So our brain combines the red, blue, and green frequencies to allow us to see about ten million color variations.
Consider how much of our world is green. Green is very soothing compared to reds or blues, but it would be dull and boring if we could see nothing but green. Seeing colors can change our mood, causing us to become relaxed or excited. Colors can convey a message or bring back memories. Different colors appeal differently to various people.
The color of our eyes, hair, or skin is part of what makes each person unique and part of God’s human tapestry. Therefore, we should thank God for the amazingly complex physical laws and biological properties that bring color into the world for us to enjoy.
