Different light colors:
Natural light has a broad band spectrum, meaning it consists of different spectra of packets with different wavelengths and hence frequencies. When this broad band is filtered using color absorbers (i.e. a material, which will scatter light), the only light with specific transmission spectrum, depending on the characteristics of the absorber will be transmitted. Visible light spectrum is categorized on clusters based on the transmitted wavelengths; thus there will be different colors. Among these are primary colors and some others (secondary) can essentially be formed from a mixture of primary colors.
Different ice-cream flavors:
The distinction of these essentially depends on an individual’s tastebud and different combination of different contents will be registered on the human brain to distinguish between the flavor as the sensory nerve relay it.
Different people in African having different skin color tones:
That is purely genetics. One can be a skin color carrier, which may only show up in a 100th generation. To use simpler terms, the strength of the color of the skin will depend on whose genes are strong among the two mates. And of course, there are also other external influences that may cause divergence in the expected skin color.
