There is a skin tone between Indians and Britishers because Indians eat different type of cuisine which Britishers don't eat the food. Indians live in a different climate and Britishers live in a different climate than Indians, that is why there is a difference between skin tone in Indians and Britishers.

Genetics decide the skin colour of Indians,
Indians have different skin colour, ranging from wheatish to light black? The skin colour in India changes from region to region. Scientists at the Hyderabad-based Centre for Cellular and Molecular Biology (CCMB) have decoded the secret behind the variation in the skin colour of Indians. They have established a genetic link to to colour difference.
The CCMB team led by senior scientist Dr Kumarasamy Thangarajin collaboration with Estonian Biocentre, Estonia, and five other research institutes carried out extensive skin survey of about a thousand individuals from across 27 populations to arrive at the fact that it is genetics that determine the skin colour. The research study was published in the latest issue of The Journal of Investigative Dermatology.
"We have done extensive epidemiological survey of 1167 individuals belonging to 27 populations and quantified melanin content at most exposed and low exposed area of human body at the middle region of Gangatic plains(Uttar Pradesh and Bihar), and selected 374 individuals for the first round of genetic study", said Dr Anshuman Mishra, the first author of the study.
According to the researchers, there is a gene called SLC24A5 that is known to make skin lighter. The gene explains about 25-38% of the pigmentation differences between Europeans and West Africans. The research team analysed the entire gene and found another variant (rs2470102), which contributes to skin pigmentation variation in Indian subcontinent. Further analyses revealed that both the variants (rs2470102 and rs2470102, discovered earlier) together could better explain the variation in skin colour among Indian populations than considering each variant independently.
