The correct answer highlights the primary biological factors that influence skin color and tone, which are melanin levels, blood flow, and skin thickness. Melanin is the pigment responsible for the various shades of skin color, with different individuals producing varying amounts based on genetic factors. Areas of increased blood flow can give the skin a flushed or rosy appearance, while reduced circulation may lead to a paler tone. Additionally, the thickness of the skin can affect the way color presents; for example, thinner skin may appear more translucent, allowing underlying blood vessels to show through more prominently, which can alter the perceived color of the skin.

These biological aspects provide a foundational understanding of skin color that is critical for professionals in the beauty and cosmetology fields. While diet choices and skin care products can influence the health and appearance of the skin, the inherent characteristics of melanin, blood circulation, and skin structure play a more direct role in determining an individual's baseline skin color and overall tone. Age can affect skin characteristics over time but is not a direct influence on the baseline skin color itself like the selected answer.
