Does red-light from sunlight effect the color of our skin

I read that red light from sunlight penetrates the skin deeper than any color. Our skin colors seem to range from a scale or red (light cream to dark brown)

1. Over the years of human history, Does red light have an impact on our genes to how melantonin determines our skin color?

2. In addition, what would happen to the skin tone of humans if blue light penetrated our skin the deepest from the sunlight?
Do you think our skin color would look different or the flesh would feel different?
