Urine sample

Urination is an everyday call of nature. Most people excrete urine yellowish or straw in colour while others have it as clear as drinking water.

The question is why is the urine yellowish in colour?

Scientifically, urine is composed of a pigment known as urochrome or urobilin which appears to be yellow, straw or amber.

The color appearance of urine depends on the concentration of this pigment. 

The human body functions best when it is properly hydrated.

When one takes a lot or enough amount of water, the pigment gets diluted and the urine excreted appears clear or less yellowish.

It should also be noted that it is not only this pigment that alters the color of urine but also the chemical composition of the food one eats.

Certain changes in the colour of urine may also mark underlying medical conditions. 

So what is the normal colour of urine?

Everybody has their own normal colour of urine although, it should fall on the yellow spectrum depending on the amount of water one takes.

 Those who take enough amounts of water are hydrated and have pale yellow urine while those who take less water have dehydrated bodies hence deep yellow or amber urine colours.
