Light and color
For the visible spectrum of light, different wavelengths, frequencies, and energies correspond to the manifestation of different colors. Visible light with the greatest wavelengths, lowest frequencies, and lowest energies appear red. Conversely, visible light with the shortest wavelengths, highest frequencies, and highest energies appear violet. The rest of the color spectrum falls in between these two ends, and they all have their own wavelength, frequency, and energy values.

All electrons of all atoms have their own natural frequency. If a light wave with a certain frequency shines on an object with a matching natural frequency, it will be absorbed by the object and transformed into thermal energy. If the light wave has a frequency that does not match that of the object, it will be reflected by the object. Due to this, objects appear the colors they are able to reflect.

White light contains all the colors of the visible spectrum. When white light shines on objects, they absorb and reflect certain colors based on their molecular make up.

When white sunlight shines on grass, the grass appears green because the molecules its composed of are able to reflect green wavelengths while absorbing all other wavelengths.

This is why it is difficult to see color in the dark. When there is no light to shine on objects, they are unable to reflect any type of light. As a result, they appear dark.

Additionally, if a red light was shone on green grass, the grass would appear black. This is because the molecules that make up the grass are only able to reflect green wavelengths. A red wavelength would be absorbed by the grass, and no color would be reflected.
