The main factors that determine skin colour are genetics and environment. Genetics plays the primary role in determining skin colour, but environmental factors such as sun exposure and diet can also affect it.
In India, the main genetic factors that determine skin colour are the levels of melanin in the skin. Melanin is a pigment that is responsible for giving skin its colour. The more melanin a person has, the darker their skin colour will be.
Environmental factors can also affect skin colour. For example, people who live in sunny climates tend to have darker skin than people who live in cloudy climates. This is because the sun's UV rays stimulate the production of melanin.
Diet can also affect skin colour. Foods that are rich in antioxidants can help to protect the skin from the sun's UV rays and prevent skin damage.
The different types of human skin colour in India can be classified into three main groups:
- Light-skinned people: These people have fair skin and light-coloured eyes and hair. They are most commonly found in the northern parts of India.
- Medium-skinned people: These people have olive skin and brown or black eyes and hair. They are most commonly found in the central parts of India.
- Dark-skinned people: These people have dark brown or black skin and brown or black eyes and hair. They are most commonly found in the southern parts of India.
The different shades of human skin colour in India are a beautiful reflection of the country's diversity. India is a country where people of all colours can live together in harmony.
