Explanation:
We can only see objects that reflect light into our eyes, and the color we see depends on the wavelengths of light that are reflected. The light we perceive as “cool” includes more blue, whereas “warm” light is more yellowish light. The color of a light source can be described by measuring the relative powers of various wavelengths.
Of all the colors in a rainbow or sunlight, violet has the highest energy. In fact, purple is the most abundant color in the atmosphere but our eyes see blue more because we are more sensitive to blue than purple. The order of colors in light, arranged from shortest wavelength to longest, is called the visible spectrum of light (red, orange, yellow, green, blue, indigo, violet)
