From a mostly scientific standpoint, color, and sight itself is how our
brains process the stimulus of light hitting the retina in our eyes. As I remember it, there are rod and cone shaped structures that respond to different wavelengths of light. This causes the optic nerve to send the information to our brain. Our brain interprets this as shapes and colors. There are many ways of ‘fooling’ this behavior. These are commonly called optical illusions, and gives us clues as to how it works.
A similar thing happens with sound. Sound is how our brains interpret the stimulation of our ears. Without ears (and brains, etc), vibration would be just vibration. It is our brains that cause us to ‘hear’ it as sound. There is an old common science class question about whether trees falling makes a sound. The point of the question was whether there was anything that could
hear the sound.
The Bible uses the universe God made to illustrate many things about Him. Knowing the mechanics of how it is done should not detract from our gratitude to Him for those wonders.
Romans 1:20 (NASB): For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse.
God made the universe for us to examine and through that examination to learn about Him.
