Hazel eyes have a higher concentration of melanin (pigment) around the eye's border, which can result in a multi-colored appearance that varies between copper and green depending on the lighting. Most people estimate that around 5-8% of the world's population has hazel colored eyes. Blue eyes are genetically recessive, and therefore much less common worldwide. Blue eyes are formed by the absence of pigments in the eye, where the blue color is formed by the scattering of light as it's reflected off the iris.
Eye color can also change depending on the light. For example hazel eyes may look different in indoor and outdoor light. Since hazel eyes often change color, people with hazel eyes are said to be unpredictable and fun loving. This is a common stereotype associated with this eye color. Green eyes are said to be mischievous and since hazel eyes can have elements of green, they also carry this stereotype.
