Color is different wavelengths of light. The eye can discriminate between them, in the same way that your fingers can discriminate between different textures, or, when feeling something three dimensional, different depths. Except, when you have eyes, you can determine these things from a distance. You don’t have to be close enough to touch them. In that way, it’s like sound.
You can tell the size of the room and how far away the walls are using sound. You don’t have to be close enough to touch the walls. Similarly, you can feel heat, which can tell you which direction the heat source is.
There are many wavelengths of radiation in the world. Eyes can only see a portion of them. We have to build machines that can detect and intrepret other wavelengths. Some of those machines are based on sound. We can use sound to detect the exact shape and distance of things from a distance. If the machines are accurate enough in interpreting the signals, we can see both surfaces and insides of things. The machines display this information by building facsimiles of what they detect.
Eyes are like these detection machines, except they are natural. They detect visual light wavelengths, and our brains interpret that information in a way that allows us to determine the nature of things from a distance. Like most senses, vision sometimes fools us, or we sometimes misinterpret what we see.
Hope that helps.
